Benzyltriethylammonium tetrathiomolybdate: An improved sulfur transfer reagent for the synthesis of disulfides

Benzyltriethylammonium tetrathiomolybdate has been found to be a superior reagent for the conversion of alkyl halides to the corresponding disulfides in chloroform at room temperature.

Trisulfides over disulfides: Highly selective synthetic strategies, anti-proliferative activities and sustained H2S release profiles

Temperature-and solvent-induced selective synthesis of trisulfides and disulfides is demonstrated. A remarkable selectivity was achieved using Na2S as a sulfur-Transfer agent under mild, greener, catalyst-free and additive-free conditions. This study reveals trisulfides as a better model than disulfides in general for a sustained release of H2S and potent anti-cancer activities.

Diarylmethylene disulfide compound as well as preparation method and application thereof

The invention relates to the technical field of medicines and in particular relates to a diarylmethylene disulfide compound as well as a preparation method and application thereof. An experiment result shows that on a cell model, the diarylmethylene disulfide compound provided by the invention has an effect of inhibiting neurotoxicity caused by excessive glutamic acid and an effect of inhibiting neurotoxicity caused by hydrogen peroxide; the diarylmethylene disulfide compound also has a platelet aggregation resisting effect and can be used for reducing a cerebral infarct area in a mouse MCAO (Middle Cerebral Artery Occlusion) model. The results show that the diarylmethylene disulfide compound provided by the invention can have prevention and/or treatment effects on cerebral stroke.

Substituent effects on the TiO2 photosensitized oxidation reaction of benzyl thioethers and thiols in deaerated acetonitrile

The TiO2 photosensitized oxidation of benzyl methyl sulfides (X-C6H4CH2SCH3) and benzyl thiols (X-C6H4CH2SH) has been investigated in Ar-saturated CH3CN. Steady-state irradiation produced benzaldehydes or dibenzylsulfides as oxidation products with sulfides and thiols, respectively. The results obtained through kinetic competitive experiments, aimed to evaluate the ring substituent effect on the reactivity, suggested the involvement of radical cation intermediates, formed by the favorable electron transfer from the substrate to the TiO2 photogenerated hole, which reasonably deprotonate to give the final products. This process was poorly affected by the adsorption of the substrate at the TiO2 surface, as demonstrated by similar results, both in terms of products and reactivity, collected for the homogeneous photooxidation of the same substrates sensitized by N-methoxyphenanthridinium hexafluorophosphate (MeOP+PF6-). This behavior is likely due to the low hydrogen-bond acceptor ability of divalent sulfur systems. Density functional theory calculations pointed out that the most stable conformations of X-C6H4CH2SH+? are characterized by having the C-S bond almost collinear with the π system of the aromatic ring and by a significant charge and spin delocalization involving both the phenyl ring and the sulfur atom.

Imidazole Promoted Highly Efficient Large-Scale Thiol-Free Synthesis of Symmetrical Disulfides in Aqueous Media

A highly efficient and environmentally friendly method for the imidazole promoted preparation of symmetrical organic disulfides from Bunte salts is described. This thiol-free procedure produces the desired disulfides even on a large scale by reaction of Bunte salts with imidazole in good to high yields in aqueous media.

Reaction of carbon black with diazonium salts, resultant carbon black products and their uses

Processes for coloring a fiber or textile by adding a carbon black product having an organic group attached to the carbon black. In one process at least one diazonium salt reacts with a carbon black in the absence of an externally applied electric current sufficient to reduce the diazonium salt. In another process at least one diazonium salt reacts with a carbon black in a protic reaction medium. Carbon black products which may be prepared according to process of the invention are described as well as uses of such carbon black products in plastic compositions, rubber compositions, paper compositions, and textile compositions.
