efficient for the oxidation of alcohols to carbonyl compounds, for the oxidative coupling of mercaptans into disulfides 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
