Results of oxidation of thiols to disulfides with molecular bromine on silicagel solid support are reported. The procedure utilizes organic media and does not require a base to neutralize HBr by-products to suppress acid promoted side reactions. Utilization of silicagelsupport simplifies work up and product isolation.

Abstract Benzyltriphenylphosphonium dichromate could be used for oxidation of organic compounds such as alcohols, thiols and sulfides to the corresponding carbonyl, disulfide and sulfoxide derivatives under solid-phase conditions. This reagent is very easily prepared from an aqueous solution of benzyltriphenylphosphonium chloride with CrO3 in 3 N HCI at room temperature. The reagent, is a stable orange
Different types of thiols were rapidly and efficiently converted to disulfides using DMSO in the presence of catalytic amounts of either trimethylchlorosilane (TMSCl) or cyanuric chloride (CC).
