Alinezhad, Heshmatollah; Pakzad, Khatereh published the artcile< C-S Cross-coupling reaction using novel and green synthesized CuO nanoparticles assisted by Euphorbia maculata extract>, Recommanded Product: 2-(Phenylthio)ethanol, the main research area is copper oxide nanoparticle green catalyst preparation; aqueous Euphorbia maculata copper sulfate extract green biosynthesis; thioether preparation green chem; thiol aryl halide cross coupling CuO nanoparticle catalyst.

In the present study, biosynthesis of CuO nanoparticles using a rapid, eco-friendly, cost-effective and efficient method was reported employing aqueous Euphorbia maculata extract as mild, renewable and non-toxic reducing and capping agents without adding any surfactants. This biogenic and green method had some benefits compared to conventional phys. and chem. methods. The biosynthesized CuO NP displayed a color change pattern (from sky blue to black) on preparation and presented its resp. broad peak at 365 nm, which was analyzed by UV-vis spectroscopy. Using FT-IR anal., biomols. in E. maculata extract which were responsible for bioreduction activity and synthesized CuO NP, were identified. XRD, EDX and FESEM results confirmed successful synthesis of CuO nanoparticles of 18 nm sizes, with spherical and sponge crystal structure. Catalytic activity of biosynthesized CuO NPs was studied in C-S cross-coupling reaction of thiols with aryl halides. This method had the advantages of high yields, easy work-up, and simple reusability. The recovered CuO NP could be reused four times without any considerable loss of its catalytic activity.

Boehmite (BO) nanoparticles (NPs) were prepared via the injection of aqueous NaOH solution to aqueous aluminum nitrate solution at room temperature Afterwards, a new complex of copper was immobilized on BO-NPs (Cu-Guanidine@BO-NPs). This heterogeneous nanocatalyst was used as a practical, recyclable, chemo and homoselective nanocatalyst in the organic processes, i.e. the preparation of tetrazole five-membered heterocycles and chemoselective sulfoxidation of sulfides using H2O2 as oxidant. In this sense, the prepared nanocatalyst was characterized by AAS, N2 adsorption-desorption isotherms, WDX, EDS, SEM, and TGA techniques. The reusability of this catalyst was investigated in the described organic reactions for several runs without notable loss of its catalytic activity. Moreover, all of the tetrazole and sulfoxide derivatives were isolated in high Turn Over Number (TON) and Turn Over Frequency (TOF) numbers indicating the high activity and selectivity of Cu-Guanidine@BO-NPs in the described reactions.

Ahmed, Kabirun; Saikia, Gangutri; Paul, Sivangi; Baruah, Satyajit Dey; Talukdar, Hiya; Sharma, Mitu; Islam, Nashreen S. published the artcile< Water-soluble polymer anchored peroxotitanates as environmentally clean and recyclable catalysts for mild and selective oxidation of sulfides with H2O2 in water>, Application In Synthesis of 699-12-7, the main research area is sulfoxide sulfone green preparation peroxotitanate polymer recyclable catalyst; sulfide selective oxidation.

Anchoring of peroxotitanium (pTi) species to linear water-soluble acrylic acid based polymers, poly(sodium acrylate) (PA) and poly(sodium methacrylate) (PMA) led to the successful synthesis of a pair of new, water-tolerant and recyclable catalysts of the type [Ti2(O2)2O2(OH)2]4–L (L = PA or PMA), highly effective in chemoselective sulfoxidation of organic sulfides I (R = C6H5, Me, 4-MeC6H4, etc.; R’ = Me, C6H5, Bn, etc.) with 30% H2O2 in aqueous medium at ambient temperature The catalytic protocol is high yielding (TOF up to 11,280 h-1), operationally simple as well as environmentally clean and safe, being free from halide, or any other toxic auxiliaries. The catalysts are sufficiently stable to afford easy recyclability for at least 10 consecutive reaction cycles of sulfoxidation with consistent activity selectivity profile. Oxidation of dibenzothiophene (DBT) to resp. high purity sulfoxide or sulfone could also be accomplished using the same catalysts by variation of reaction conditions.

Chen, Yanhong; Chang, Shenzhen; An, Haiyan; Li, Yanqin; Zhu, Qingshan; Luo, Huiyun; Huang, Yaohui published the artcile< Two Polymorphic Polyoxometalate-Based Metal-Organic Frameworks for the Efficient Synthesis of Functionalized Sulfoxides and Detoxification of Mustard Gas Simulants>, Electric Literature of 699-12-7, the main research area is zinc bipyridine polyoxometalate MOF preparation crystal structure oxidation catalyst; XPS zinc bipyridine polyoxometalate MOF.

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.

A mild and facile Cp*Rh(III)-catalyzed C-H activation and intramol. cascade annulation protocol has been proposed for the furnishing of highly fused isochromeno-1,2-benzothiazines I (R1 = H, 2-Me, 2-F, 4-Br, 3-OMe, (CH2)4, etc.; R2 = Me, Et, Ph, Bn, etc.; R3 = H, 10-Me,10-OMe, 11-Cl, 11-F, etc.) scaffolds using S-phenylsulfoximides R4C6H4S(O)(=NH)(R2) and 4-diazoisochroman-3-imine II (R5 = H, 7-Me, 6-OMe, 7-OMe, 6-Cl, etc.) as substrates under room temperature This method features diverse substituents and functional groups tolerance and relatively mild reaction conditions with moderate to excellent yields. Addnl., retentive configuration of sulfoximides in the conversion has been verified.

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.
