common methods including, FT-IR, XRD, EDX, SEM and then used as an efficient and recyclable catalyst for the direct synthesis of symmetric organic disulfides. A variety of symmetric diaryl disulfides with high chemoselectivity can be obtained by domino reaction of aryl halides (and tosylates) and potassium 5-methyl-1,3,4-oxadiazole-2- thiolate, as the base and sulfur-transfer reagent, in the presence

A new method is reported for the synthesis of symmetric diaryl and dialkyl disulfidesfrom aryl and alkyl halides in the presence of copper using potassium 5-methyl-1,3,4-oxadiazole-2-thiolate as the base, ligand, and sulfur-transfer reagent.

ArS(ArSSAr)+ (arylbis(arylthio)sulfonium ions), which were generated and accumulated by the electrochemical oxidation of diaryl disulfides (ArSSAr) in CH2Cl2 at −78 °C, reacted with alkenes to give the corresponding diarylthio-substituted compounds in a stereospecific manner in good yields, when the reaction was quenched with a soft nucleophile, such as allylsilanes, ketene silyl acetals, and triethylamine

We developed hydroxysulfurization and alkoxysulfurization of styrenes using a visible‐light synthetic strategy in the absence of photocatalyst and oxidant. This strategy provided the corresponding β‐hydroxysulfides and β‐alkoxysulfides in moderate to good yields with high regioselectivity. The reaction was tolerated by a wide range of functional groups. This is the first example of ArSSAr/CBr4 system
