So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Tosolini, Massimo; Avo, Joao; Parola, Antonio Jorge; Balducci, Gabriele; Tecilla, Paolo researched the compound: Dichloro(1,5-cyclooctadiene)platinum(II)( cas:12080-32-9 ).Name: Dichloro(1,5-cyclooctadiene)platinum(II).They published the article 《Sterically Encumbered 4,5-Bis(diphenylphosphino)acenaphthene Ligand and Its Ni(II), Pd(II), Pt(II), and Cu(I) Complexes》 about this compound( cas:12080-32-9 ) in European Journal of Inorganic Chemistry. Keywords: sterically encumbered diphenylphosphinoacenaphthene ligand preparation crystal mol structure complexation; nickel palladium platinum copper diphenylphosphinoacenaphthene preparation crystal mol structure. We’ll tell you more about this compound (cas:12080-32-9).

A new sterically encumbered sym. substituted 4,5-bis(diphenylphosphino)acenaphthene ligand (L) has been prepared The ligand readily forms distorted square-planar complexes with group 10 metal ions [Ni(II), Pd(II), Pt(II)] and a dimeric tetrahedral complex with Cu(I). The x-ray structures of the ligand and of the complexes show a notably short distance between the two phosphorus atoms, well below than twice the van der Waals radius of P, due to the steric requirements of the rigid acenaphthene backbone. Moreover, in the complexes a stabilizing π-π interaction between two Ph rings belonging to the two P atoms is present. The [LCuCl]2 complex is weakly fluorescent both in solution and in the solid state with higher quantum yield as a solid where it exhibits thermally-activated delayed fluorescence and phosphorescence. [LPdCl2] and [LCuCl]2 behave as chloride transporters across a liposomal phospholipid membrane with the Pd(II) complex displaying a very high activity.

Quality Control of Dichloro(1,5-cyclooctadiene)platinum(II). The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Understanding Doping Effects on Electronic Structures of Gold Superatoms: A Case Study of Diphosphine-Protected M@Au12 (M = Au, Pt, Ir). Author is Hirai, Haru; Takano, Shinjiro; Nakamura, Toshikazu; Tsukuda, Tatsuya.

Dopants into ligand-protected Au superatoms have been hitherto limited to group X-XII elements (Pt, Pd, Ag, Cu, Hg, and Cd). To expand the scope of the dopants to the group IX elements, the authors synthesized unprecedented [IrAu12(dppe)5Cl2]+ [IrAu12; dppe = 1,2-bis(diphenylphosphino)ethane] and [PtAu12(dppe)5Cl2]2+ (PtAu12) and compared their electronic structures with that of [Au13(dppe)5Cl2]3+ (Au13). Single-crystal x-ray diffractometry, 31P{1H} NMR, and Ir L3-edge extended X-ray absorption fine structure anal. of IrAu12 revealed that the single Ir atom is located at the center of the icosahedral IrAu12 core. Electrochem. anal. demonstrated that the energy levels of the highest occupied MOs are upshifted in the order of Au13 < PtAu12 < IrAu12. This trend was qual. explained in such a manner that the jellium core potential at the central position becomes shallower by replacing Au+ with Pt0 and further with Ir-. IrAu12 underwent reversible redox reactions between the charge states of 1+ and 2+. The gradual increase of the energy gap between the HOMO and LUMO in the order of Au13 < PtAu12 < IrAu12 was observed by electrochem. measurement and optical spectroscopy. This study provides a simple guiding principle to tune the electronic structures of heterometal-doped superatoms. The orbital energies of [IrAu12(dppe)5Cl2]+ (IrAu12) and [PtAu12(dppe)5Cl2]2+ (PtAu12) were compared with those of [Au13(dppe)5Cl2]3+ (Au13) by electrochem. anal. The superat. orbitals were shifted up in the order of IrAu12 > PtAu12 > Au13. The result was explained by the upshift of the bottom of the effective potential due to different formal charge states of the dopants. Whereas Au was incorporated as Au+, Ir and Pt were incorporated as Ir- and Pt0, resp.

Application In Synthesis of Dichloro(1,5-cyclooctadiene)platinum(II). So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about 2-Adamantyl Complexes of Platinum.

The first adamantyl platinum complexes were isolated and characterized, namely [(COD)Pt(2-Ad)Cl], [(dppe)Pt(2-Ad)Cl], [(COD)Pt(2-Ad)Me] and, [(dppe)Pt(2-Ad)Me] {COD = 1,5- cyclooctadiene, dppe = 1,2-bis(diphenylphosphino)ethane, Ad = adamantyl}. These complexes show considerable stability, including resistance to heating to 125° in solution for several days. It is therefore concluded that previously existing road blocks to synthesizing platinum adamantyls were due to complications in the transmetalation step, and not due to intrinsic instability of the final product. Counterintuitively, the key to successful transmetalation from ZnII onto PtII is imposing slow reaction progress via use of a solvent in which both the platinum chloride precursor and adamantyl anion precursor are poorly soluble

Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:12080-32-9) here.

Herein the authors report the synthesis and characterization of a linear, two-coordinate Pt(II) ketimide complex, Pt(N:CtBu2)2 (1), formed via the reaction of PtCl2(1,5-COD) with 2 equiv of Li(N:CtBu2). Also generated in the reaction is the bimetallic complex [(tBu2C:N)Pt(μ-N,C-N:C(tBu)C(Me)2CH2)Pt(N:CtBu2)] (2). Both complexes 1 and 2 were characterized by NMR spectroscopy and x-ray crystallog. Notably, complex 1 exhibits short Pt-N distances (average Pt-N = 1.817 Å) and an unusually deshielded 195Pt chem. shift (δPt = -629 ppm) with a large 1J(195Pt,14N) coupling constant (537 Hz). These data, in combination with a detailed d. functional theory electronic structure anal., reveal highly covalent Pt:N multiple bonds formed by a combination of σ-donation, π-donation, and π-backdonation. Pt(N:CtBu2)2 represents the 1st linear Pt(II) complex to be reported, expanding the scope of Pt(II) coordination chem. beyond the more common square planar and T-shaped geometries.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Chemoresponsive Shape-Memory Effect of Rhodium-Phosphine Coordination Polymer Networks.Category: alcohols-buliding-blocks.

Chemoresponsive polymers are of technol. significance for smart sensors or systems capable of mol. recognition. An important key requirement for these applications is the material’s structural integrity after stimulation. We explored whether covalently crosslinked metal ion-phosphine coordination polymers (MPN) can be shaped into any temporary shape and are capable of recovering from this upon chemoresponsive exposure to triphenylphosphine (Ph3P) ligands, whereas the MPN provide structural integrity. Depending on the metal-ion concentration used during synthesis of the MPN, the degree of swelling of the coordination polymer networks could be adjusted. Once the MPN was immersed into Ph3P solution, the reversible ligand-exchange reaction between the metal ions and the free Ph3P in solution causes a decrease of the coordination crosslink d. in MPN again. The Ph3P-treated MPN was able to maintain its original shape, indicating a certain stability of shape even after stimulation. In this way, chemoresponsive control of the elastic properties (increase in volume and decrease of mech. strength) of the MPN was demonstrated. This remarkable behavior motivated us to explore whether the MPN are capable of a chemoresponsive shape-memory effect. In initial experiments, shape fixity of around 60% and shape recovery of almost 90% were achieved when the MPN was exposed to Ph3P in case of rhodium. Potential applications for chemoresponsive shape-memory systems could be shapable semiconductors, e.g., for lighting or catalysts, which provide catalytic activity on demand.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 12080-32-9, is researched, SMILESS is C1=CCC/C=CCC/1.[Pt+2].[Cl-].[Cl-], Molecular C8H12Cl2PtJournal, Synlett called Confining the Inner Space of Strained Carbon Nanorings, Author is Grabicki, Niklas; Dumele, Oliver, the main research direction is cyclopyrenylene macrocycle confining inner space strained carbon nanoring preparation; crystal mol structure cyclopyrenylene macrocycle carbon nanoring.Synthetic Route of C8H12Cl2Pt.

Strained aromatic macrocycles based on cycloparaphenylenes (CPPs) are the shortest repeating units of armchair single-walled carbon nanotubes. Since the development of several new synthetic methodologies for accessing these structures, their properties have been extensively studied. Besides the fundamental interest in these novel mol. scaffolds, their application in the field of materials science is an ongoing topic of research. Most of the reported CPP-type macrocycles display strong binding toward fullerenes, due to the perfect match between the convex and concave π-surfaces of fullerenes and CPPs, resp. Highly functionalized CPP derivatives capable of supramol. binding with other mols. are rarely reported. The synthesis of highly functionalized [ n]cyclo-2,7-pyrenylenes leads to CPP-type macrocycles with a defined cavity capable of binding non-fullerene guests with high association constants

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 12080-32-9, is researched, Molecular C8H12Cl2Pt, about Ditopic dithiocarbamate ligands for the production of trinuclear species, the main research direction is ditopicdipicolyl dithiocarbamate nickel palladium platinum zinc preparation crystal structure; crystal mol structure dipicolyldithiocarbamate nickel palladium platinum zinc complex.Recommanded Product: Dichloro(1,5-cyclooctadiene)platinum(II).

Reactions of group 10 transition metals with the ditopic ligand dipicolyldithiocarbamate (DPDTC) were performed. Thus, 1:2 reactions of [Ni(CH3COO)2], [Pd(COD)Cl2] or [Pt(COD)Cl2] with DPDTC produced monomeric complexes of the type [M(κ2-SCS-DPDTC)2, M = Ni (1), Pd (2) or Pt (3)] with the dithiocarbamate ligand (DTC) coordinated in a typical chelate κ2-SCS fashion. Interestingly, the reaction of [NiCl2] with DPDTC, under similar conditions, afforded the organic compound 2-(pyridin-2-ylmethyl)imidazo[1,5-a]pyri-dine-3(2 H)-thione (4) as unique product. In order to prove the ditopic nature of the ligand DPDTC, complex [Pd(κ2-SCS-DPDTC)2] (2) was further reacted with [ZnCl2] in a 1:2 M ratio to yield the trinuclear complex [Cl2Zn(κ2-NN-DPDTC-SCS-κ2)Pd(κ2-SCS-DPDTC-NN-κ2)ZnCl2] (5). The mol. structures of all compounds were determinate by typical anal. techniques including the unequivocal determination of all structures by single crystal x-ray diffraction anal. As expected, complexes 1-3 are isostructural, and the metal centers exhibiting slightly distorted square-planar geometries.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Mustards-Derived Terpyridine-Platinum Complexes as Anticancer Agents: DNA Alkylation vs. Coordination, published in 2021-02-15, which mentions a compound: 12080-32-9, Name is Dichloro(1,5-cyclooctadiene)platinum(II), Molecular C8H12Cl2Pt, Name: Dichloro(1,5-cyclooctadiene)platinum(II).

The development of bifunctional platinum complexes with the ability to interact with DNA via different binding modes is of interest in anticancer metallodrug research. Therefore, we report platinum(II) terpyridine complexes to target DNA by coordination and/or through a tethered alkylating moiety. The platinum complexes were evaluated for their in vitro antiproliferative properties against the human cancer cell lines HCT116 (colorectal), SW480 (colon), NCI-H460 (non-small cell lung), and SiHa (cervix) and generally exhibited potent antiproliferative activity although lower than their resp. terpyridine ligands. 1H NMR spectroscopy and/or ESI-MS studies on the aqueous stability and reactivity with various small biomols., acting as protein and DNA model compounds, were used to establish potential modes of action for these complexes. These investigations indicated rapid binding of complex PtL3 to the biomols. through coordination to the Pt center, while PtL4 in addition alkylated 9-ethylguanine. PtL3 was investigated for its reactivity to the model protein hen egg white lysozyme (HEWL) by protein crystallog. which allowed identification of the Nδ1 atom of His15 as the binding site.

Author is Liska, Tadeas; Swetz, Anna; Lai, Po-Ni; Zeller, Matthias; Teets, Thomas S.; Gray, Thomas G..

The use of organometallic triplet emitters in organic light emitting diodes (OLEDs) is motivated by the premise of efficient intersystem crossing leading to unit internal quantum efficiencies. However, since most devices are based on solid-state components, an inherent limitation to square-planar Pt(II) phosphors is their tendency toward aggregation-based quenching. Here, a new class of emissive, four-coordinate Pt(II) species based on the bisimidazolyl carbazolide (BIMCA) ligand is introduced, which displays highly efficient, long-lived solid-state phosphorescence at room temperature A set of four BIMCAPt Ph acetylides were synthesized that emit in the green (λmax=507-540 nm) with >60% quantum yield and millisecond lifetimes. The structures of the resulting species reveal a nonplanar structure imposed by steric clashes between BIMCA and the iodo or alkynyl co-ligand. Ground-state and photophys. characterization are presented. D. functional theory calculations indicate that the BIMCA ligand dominates the frontier orbitals along with the 1st Franck-Condon singlet and triplet excited states.

The new ferrocene based bisphosphine [Fe{C5H4P(CCPh)2}2] (1) was synthesized in 82% yield by the treatment of bis(dichlorophosphino)ferrocene [Fe(C5H4PCl2)2] with four equivalent of lithium phenylacetylide. The reactions of 1 with aqueous H2O2, elemental sulfur or selenium afforded bis(chalcogenide) derivatives, [Fe{C5H4P(E)(CCPh)2}2] (2 E = O, 3 E = S, 4 E = Se). The reaction of 1 with [M(NC5H11)2(CO)4] (M = Mo, W), [RuCp(PPh3)2Cl] and [M(COD)Cl2] (M = Pd, Pt) resulted in the formation of the resp. chelate complexes, [Fe{C5H4P(CCPh)2}2{M(CO)4}] (5 M = Mo, 6 M = W), [Fe{C5H4P(CCPh)2}2{RuCp(Cl)}] (8) and [Fe{C5H4P(CCPh)2}2{MCl2}] (9 M = Pd, 10 M = Pt), whereas the reaction of 1 with [Ru(η6-p-cymene)Cl2]2 and [AuCl(SMe2)] yielded the corresponding bimetallic complexes [Fe{C5H4P(CCPh)2}2{RuCl2(η6-p-cymene)}2] (7) and [Fe{C5H4P(CCPh)2}2{AuCl}2] (15).
