The development of high-efficient catalysts for the oxidation reaction of sulfides received much attention in recent years due to the extensive applications of such reactions from the utility in pharmaceutical chem. and biol. to the detoxification of chem. warfare agents in war. Herein, the authors report two innovative polyoxometalate-based metal-organic frameworks (POMOFs) {[ε-PMoV8MoVI4O37(OH)3][Zn2(C10N2H8)(H2O)2]2}2·8H2O (1-α and 1-β), which were characterized by elemental anal., UV-visible diffuse reflectance spectroscopy, x-ray single-crystal and powder diffraction, XPS, and FTIR spectroscopy techniques. Single-crystal x-ray diffraction anal. indicates that 1-α and 1-β are polymorphic with the identical compositions and analogical structures. Compounds 1-α and 1-β are both connected by Zn4-ε-Keggin polyoxoanions and 4,4′-bipyridine (bpy) ligands to form twofold interpenetrated three-dimensional POMOF structures. 1-β can be seen as a rotational polymorph of 1-α, i.e., 1-α takes the b axis as the rotation axis and rotates ~39° clockwise to obtain 1-β. Both compounds 1-α and 1-β can be used as heterogeneous catalysts to catalyze the selective oxidation of multitudinous sulfides with H2O2 as an oxidant. When the oxidation of Me Ph sulfide was used as the template reaction, the yield of Me Ph sulfoxide is ∼100% within 30 min by 1-α and 1-β and the oxidant use efficiency is >93%. Gratifying catalytic effects also were achieved in the selective oxidation of Ph and aliphatic sulfide derivatives Simultaneously, both 1-α and 1-β showed an extraordinary degradation efficiency of 2-chloroethyl Et sulfide and have a half lifetime (t1/2) ∼2.5 or 3 min, resp., with 100% selectivity toward the nontoxic product 2-chloroethyl Et sulfoxide and an abnormally high oxidant use efficiency (94.5% for 1-α and 94.3% for 1-β) at room temperature In addition, after seven cycles and continuous cycle catalytic experiments, their structures remained and catalytic activities did not decrease obviously, revealing their outstanding recyclability and structural stability.

Guan, Zhipeng; Zhu, Shuxiang; Wang, Siyuan; Wang, Huamin; Wang, Siyuan; Zhong, Xingxing; Bu, Faxiang; Cong, Hengjiang; Lei, Aiwen published the artcile< Electrochemical Oxidative Carbon-Atom Difunctionalization: Towards Multisubstituted Imino Sulfide Ethers>, COA of Formula: C8H10OS, the main research area is electrochem oxidative difunctionalization isocyanide imino sulfide ether stereoselective synthesis; electrochemistry; ethers; isocyanides; radicals; synthetic methods.

Ethers (C-O/S) are ubiquitously found in a wide array of functional mols. and natural products. Nonetheless, the synthesis of imino sulfide ethers, containing an N(sp2)=C(sp2)-O/S fragment, still remains a challenge because of its sensitivity to acid. Developed here in is an unprecedented electrochem. oxidative carbon-atom difunctionalization of isocyanides, providing a series of novel multisubstituted imino sulfide ethers. Under metal-free and external oxidant-free conditions, isocyanides react smoothly with simple and readily available mercaptans and alcs. [e.g., 4-fluorobenzenethiol + Et isocyanoacetate + methanol → (Z)-I (80% isolated)]. Importantly, the procedure exhibited high stereoselectivities, excellent functional-group tolerance, and good efficiency on large-scale synthesis, as well as further derivatization of the products.

We report the C-H activation of thioethers to α-thio alkyl radicals and their addition to electron-deficient olefins to afford alkylated products through dual photoredox and weak Bronsted base catalysis. Mechanistic studies are consistent with a two-step activation mechanism, where oxidation of thioethers to their corresponding sulfide radical cations by an acridinium photoredox catalyst is followed with deprotonation by trifluoroacetate to generate α-thio alkyl radicals and trifluoroacetic acid (TFA). Exptl. studies support the involvement of TFA in all subsequent steps leading to product formation.

Tyula, Yunes Abbasi; Zabardasti, Abedien; Goudarziafshar, Hamid; Kucerakova, Monika; Dusek, Michal published the artcile< A new supramolecular zinc(II) complex containing 4-biphenylcarbaldehyde isonicotinoylhydrazone ligand: Nanostructure synthesis, catalytic activities and Hirshfeld surface analysis>, Product Details of C8H10OS, the main research area is Hirshfeld surface analysis intermol interaction zinc biphenyl carboxaldehyde complex; sulfide selective oxidation sulfoxide preparation zinc biphenyl carboxaldehyde catalyst; crystal structure zinc dibromo biphenyl carboxaldehyde complex preparation.

A new potentially tridentate hydrazone ligand, 4-biphenylcarbaldehyde isonicotinoylhydrazone (4-bpinh), was prepared by the condensation of biphenyl-4-carboxaldehyde with isonicotinic acid hydrazide. Then, its nano-sized and single crystal of zinc complex were synthesized using sonochem. and heat gradient methods, resp. The structure of complex, [Zn(4-bpinh)2Br2] (1), was determined by single-crystal x-ray diffraction, FTIR, and elemental anal., and the nano-structure of complex was characterized by FTIR, XRD, and SEM. The single crystal x-ray structure of complex showed that the metal center has a distorted tetrahedral geometry and the hydrazone ligand acts as monodentate trough the pyridyl N atom. Moreover, the anal. of crystal structures indicates the existence of intermol. interactions such as N/C-H···Br/O, N/C-H···π, and π···π stacking in the stabilization of complex structure which finally gave the three-dimensional supramol. structure. Also, the impact of this interactions was more studied using Hirshfeld surface anal. and corresponding 2D fingerprint plots. Furthermore, the catalytic activity of 1 was studied in the selective oxidation of various sulfides to corresponding sulfoxides using hydrogen peroxide as the oxidative agent.

Zhao, Peng; El-kott, Attalla; Ahmed, Ahmed Ezzat; Khames, Ahmed; Zein, Mohamed Abdellatif published the artcile< Green synthesis of gold nanoparticles (Au NPs) using Tribulus terrestris extract: Investigation of its catalytic activity in the oxidation of sulfides to sulfoxides and study of its anti-acute leukemia activity>, Computed Properties of 699-12-7, the main research area is green preparation gold nanoparticle; XRD particle size distribution gold nanoparticle; sulfide oxidation gold nanoparticle catalyst; sulfoxide preparation catalyst gold nanoparticle; antiacute leukemia activity gold nanoparticle; antioxidant activity gold nanoparticle; cytotoxicity gold nanoparticle.

With regards to applied, facile, green chem. research, a bio-inspired approach is being reported for the synthesis of Au NPs by using Tribulus terrestris extract The innate oxygenated phytochems. facilitated the green reduction of Au3+ ions to corresponding NPs and also stabilized them by encapsulating them. This modification prevented the as-synthesized Au NPs towards agglomeration and tiny NPs were obtained in uniformly spherical in shape and at 10-15 nm dimension. Physicochem. characteristics of the green synthesized Au NPs were evaluated by advanced physicochem. techniques like UV-visible and FTIR spectroscopy, SEM, TEM, EDX and XRD study. Catalytic performance of the biomol. functionalized Au NPs was studied in the controlled and selective oxidation of sulfides to sulfoxides using hydrogen peroxide as green oxidant at room temperature Aromatic, aliphatic and heterocyclic sulfides were oxidized to their corresponding sulfoxides with high yields without formation of over oxidized sulfones. The catalyst was easily recovered and recycled for 8 successive times without noticeable decrease in catalytic activity. In addition, the biosynthesized Au NPs indicated suitable antioxidant and anti-acute leukemia properties against THP-1 cell line. Tribulus terrestris extract and the green synthesized Au NPs exhibited a maximum DPPH scavenging activity of 78% and 29.37%, resp. Again, in the anticancer studies over THP-1 cell line following MTT assay, the Au NP exhibited gradual reduced % cell viability with increase in its concentration At an Au NPs concentration of 2000μg/mL, the % toxicity became maximum suggesting efficient inhibition of cancer invasion. Based on the above results, Au NPs-Tribulus could be administered as a potential anti-leukemia drug for the treatment of acute leukemia following the clin. trial studies in humans.

A novel and reusable nanocatalyst was synthesized by anchoring a nickel Schiff base complex onto Fe3O4@MCM-41 (Fe3O4@MCM-41@Ni-P2C) and characterization was accomplished with Fourier transform IR spectroscopy (FT-IR), thermogravimetric anal. (TGA), powder X-ray diffraction (XRD), vibrating sample magnetometry (VSM), transmission electron microscopy (TEM), SEM (SEM) and at. absorption spectroscopy (AAS) techniques. This catalytic system was efficiently used for oxidation of sulfides to sulfoxides and oxidative coupling of thiols to corresponding disulfides using H2O2 as green oxidant at room temperature These reactions were carried out in a green solvent (ethanol) and/or under solvent-free conditions with short reaction time, complete selectivity and very high conversion under mild reaction conditions.

Three lanthanide (Ln)-functionalized antimonotungstate (AT) clusters with a {Sb4O4Ln3(H2O)8} core [H2N(CH3)2]14Na8H16[Sb4O4Ln3(H2O)8W2O4(H2O)2(B-α-SbW9O33)4]2·87H2O [Ln = Dy3+ (1), Ho3+ (2), Y3+ (3)] were synthesized in an acidic aqueous solution Their mol. structural unit comprises two {Sb4O4Ln3(H2O)8}-core-incorporated tetrameric [Sb4O4Ln3(H2O)8W2O4(H2O)2 (B-α-SbW9O33)4]19- polyanionic units, each of which is assembled from an unprecedented [Sb4O4Ln3(H2O)8W2O4(H2O)2]17+ heteroatom cluster surrounded by four trivacant [B-α-SbW9O33]9- subunits. What is noteworthy is that a tetrahedral {Sb4O4} cluster is located at the center of the polyanionic unit, as far as we know, which is very infrequent in multi-Ln-functionalized polyoxometalate chem. Solid-state luminescent properties and energy migration of AT ligands to Dy3+ and Ho3+ cations in 1 and 2 have been intensively probed at ambient temperature By varying the exciting wavelength from 250 to 450 nm, the emitting color could vary from blue to yellow for 1 and blue to green-yellow for 2, sep. In addition, high catalytic activities and good reusability of 2 as a heterogeneous catalyst for oxygenation reaction of sulfides have been systematically performed.

Boehmite nanoparticles are aluminum oxide hydroxide (γ-AlOOH) particles, which has large sp. surface area (>120 m2 g-1) and can be prepared using an inexpensive procedure in water. Herein, we present an economical, simple, and environmentally friendly route for the preparation of a copper catalyst on Adenine coated boehmite nanoparticles (Cu-Adenine@boehmite). This catalyst has been characterized by several techniques such as SEM, XRD, AAS, ICP and TGA anal. Cu-Adenine@boehmite was applied as highly efficient and reusable nanocatalyst in carbon-carbon coupling reactions between various aryl halides and sodium tetra-Ph borate, phenylboronic acid, or 3,4-diflorophenylboronic acid under aerobic conditions, palladium-free and phosphine-free ligand. Also this catalyst was applied for the synthesis of polyhydroquinoline derivatives In continuation, selective oxidation of sulfides to sulfoxides using hydrogen peroxide (H2O2) was studied in the presence of Cu-Adenine@boehmite as catalyst. The synthesis of sulfoxides using H2O2 in the presence of Cu-Adenine@boehmite does not generate waste and any byproducts. This catalyst was reused for several times in C-C coupling reaction without loss of its catalytic activity. Reused catalyst was characterized by SEM, XRD and ICP techniques. Heterogeneity and stability of Cu-Adenine@boehmite were studied by hot filtration test, poisoning test and ICP anal.
