The authors also want to convey more information about this compound (cas:7661-33-8) through the article.

The dipole moments of 1-phenyl-2-pyrrolidone and its 2′-methyl, 3′-methyl, 4′-methyl, 2′-chloro, 3′-chloro, 4′-chloro, 2′-methoxy, 3′-methoxy, and 4′-methoxy derivatives were measured in dioxane at 30° and the dipole moments of the 1st 4 compounds also in cyclohexane at 30°. The dipole moments were larger in dioxane than in cyclohexane. The dipole moments of all the compounds except 1-(3-methoxyphenyl)-2-pyrrolidone and 1-(4-methoxyphenyl)-2-pyrrolidone agree with the values calculated by applying Eyring’s treatment and assuming free rotation of the pyrrolidonyl group about the bond joining it to the aromatic ring.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Synthesis and structure of thienyl Fischer carbene complexes of PtII for application in alkyne hydrosilylation, the main research direction is thienyl Fischer carbene platinum complex preparation catalyst alkyne hydrosilylation; crystal structure thienyl Fischer carbene platinum complex; mol structure thienyl Fischer carbene platinum complex; Group 6 thienothienylene carbene complex transmetalation platinum chloride complex.Recommanded Product: 12080-32-9.

Transmetalation of Group 6 thienylene Fischer carbene complexes to Pt(II) precursors yielded new examples of neutral Pt(II) bisethoxycarbene complexes with either 2-thienyl (T) or 5-thieno[2,3-b]thienylene (TT) carbene substituents. The use of analogous aminocarbene group 6 precursors proceeded to give isomeric Pt(II) product mixtures where the resultant bisaminocarbene ligands displayed different orientations due to restricted rotation around the Pt-aminocarbene bond caused by the sterically demanding TT substituents. The well-defined Pt(II) ethoxycarbene complexes were screened as catalyst precursors in the benchmark hydrosilylation reaction employing phenylacetylene and triethylsilane substrates. Marked selectivity for the β-E isomer (E)-triethyl(styryl)silane was observed, and the (pre)catalysts proved recyclable, active in solvent-free reactions, and displaying a high alkyne functional group tolerance.

When p-NO2C6H4NH2 is dissolved or suspended in HCl and Cl or Br added a mixture, difficult to sep., of mono- and dihalogenated anilines with the halogen in the o-position is formed. If, however, gaseous Cl (mol. ratio 1 : 1) is passed into the b. HCl solution 2,4-Cl(O2N)C6H3NH2 is almost the sole product. This derivative mixed with some di-Cl derivative is obtained on chlorinating at -o°(Casella & Co., Ger. Pat., 109,189). At room temperature, on adding Cl slowly to the HCl solution, the di-Cl deriv, + quinone are formed. Chlorinating by Noelting’s method, using Ca(ClO)2, gave mixtures Similar results were obtained with Br. These derivatives are obtained by warming 1-nitro-3,4-dibromo (or dichloro) benzene with alc. NH3 in the scaled tube at 190°. The NH2 group substitutes p to NO2. By halogenating these monohalogen derivatives it is possible to get derivatives with 2 different halogens in the same ring. The action of ClI on a glac.

Recommanded Product: 12080-32-9. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: Dichloro(1,5-cyclooctadiene)platinum(II), is researched, Molecular C8H12Cl2Pt, CAS is 12080-32-9, about Vapochromic luminescent proton conductors: switchable vapochromism and proton conduction of luminescent Pt(II) complexes with proton-exchangeable sites. Author is Kobayashi, Atsushi; Imada, Shin-ichiro; Shigeta, Yasuhiro; Nagao, Yuki; Yoshida, Masaki; Kato, Masako.

Two luminescent and highly proton-conductive Pt(II) complexes [PtCl(tpypy)]Cl and [PtCl(tpypyH)]Cl2 (1 and 1·HCl, resp.; tpypy = 2,2′: 6′,2”-terpyridine-4′,4”’-pyridine) were successfully synthesized. X-ray anal. revealed that the intermol. Pt···Pt interaction was ineffective in the monohydrated form of 1·H2O but effective in dihydrate and hexahydrate forms, 1·HCl·nH2O (n = 2 and 6). Yellow luminescence (λem = 519 nm and Φ = 0.016) assigned to intraligand 3π-π* phosphorescence was observed for 1·H2O, whereas a stronger red emission ascribable to the phosphorescence from the triplet metal-metal-to-ligand charge transfer (3MMLCT) state was observed for the HCl adduct 1·HCl·nH2O (λem = 741 nm, Φ = 0.06 for n = 2, λem = 642 nm, and Φ = 0.10 for n = 6). Both complexes exhibited strong relative humidity (RH)-dependent proton conductivity, while surprisingly high conductivity was observed for 1·HCl (6.8 × 10-3 S cm-1) at 95% RH at 298 K. The reversible transformation between 1 and 1·HCl was achieved upon exposure to humid HCl gas and heating and their vapochromic behavior was completely different owing to the presence of acidic N-H protons and the addnl. hydrophilic Cl- counteranions in 1·HCl. To the best of the authors’ knowledge, these complexes are the first switchable vapochromic and highly proton conductive materials that can be employed to visualize the proton conducting state by color and luminescence.

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:1787246-78-9) here.

The ubiquitous structure of δ-lactones makes the development of new methods for their enantioselective and stereoselective synthesis an important ongoing challenge. The intermol. dynamic kinetic resolution (DKR) of β-halo-α-keto esters cooperatively catalyzed by an N-heterocyclic carbene and a Lewis acid generates two contiguous stereocenters with remarkable diastereoselectivity through an oxidation/lactonization sequence. Under optimized conditions the synthesis of the target compounds was achieved using (5aS,10bR)-5a,10b-dihydro-2-(2,6-diethylphenyl)-4H,6H-indeno[2,1-b][1,2,4]triazolo[4,3-d][1,4]oxazinium tetrafluoroborate (i.e., NHC, nitrogen-heterocyclic carbene) and scandium triflate as catalyst combination.

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 Platinum Atoms Dispersed in Single-chain Polymer Nanoparticles, published in 2021-04-30, which mentions a compound: 12080-32-9, Name is Dichloro(1,5-cyclooctadiene)platinum(II), Molecular C8H12Cl2Pt, Computed Properties of C8H12Cl2Pt.

The intramol. crosslinking of single polymer chains can form single-chain nanoparticles (SCNPs), which have many applications. In this study, styrenic copolymers with pendent triphenylphosphine as the coordination site for platinum ions (Pt(II)) and benzocyclobutene as the latent reactive groups are synthesized. Triphenylphosphine groups in the chains can coordinate Pt(II) and aid slight single-chain folding in dilute solution The intramol. crosslinking caused by the ring-open reaction of benzocyclobutene completes the single-chain collapse and forms stable SCNPs in dilute solution Pt(II) embedded in SCNPs can be further reduced to platinum atoms (Pt(0)). Pt(0) steadily and atomically dispersed in SCNPs exhibits better catalytic properties than normal polymer carried platinum particles do for the reduction of p-nitrophenol to p-aminophenol.

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 Platinum Atoms Dispersed in Single-chain Polymer Nanoparticles.HPLC of Formula: 12080-32-9.

The intramol. crosslinking of single polymer chains can form single-chain nanoparticles (SCNPs), which have many applications. In this study, styrenic copolymers with pendent triphenylphosphine as the coordination site for platinum ions (Pt(II)) and benzocyclobutene as the latent reactive groups are synthesized. Triphenylphosphine groups in the chains can coordinate Pt(II) and aid slight single-chain folding in dilute solution The intramol. crosslinking caused by the ring-open reaction of benzocyclobutene completes the single-chain collapse and forms stable SCNPs in dilute solution Pt(II) embedded in SCNPs can be further reduced to platinum atoms (Pt(0)). Pt(0) steadily and atomically dispersed in SCNPs exhibits better catalytic properties than normal polymer carried platinum particles do for the reduction of p-nitrophenol to p-aminophenol.
