Synthetic utility of halosilanes-chromium trioxide reagents as excellent new oxidizing agents is described.They are highly efficient for the oxidation of alcohols to carbonyl compounds, for the oxidative coupling of mercaptans intodisulfides and for a mild cleavage of oximes to carbonyl compounds.Chlorotrimethylsilane-chromium trioxide has been shown to be an efficient oxidizing agent for the conversion of arylmethanes to benzaldehydes.The reagent is applied to the oxidative cleavage of some benzyl esters.A mild procedure for the iodination of organic compounds by means of in situ generated iodonium species from this reagent and molecular iodine is also described.
