Modified polyacrylamide-supported chlorochromate was synthesized and used as a versatile and efficient oxidizingagent for the oxidation of various organic compounds, such as hydroxyl compounds, silylethers, oximes, thiols, and others. Over oxidation of the products (aldehydes to carboxylic acids) was not observed with this oxidizingagent. The oxidant was insoluble in the oxi- dation media and the

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).
