Oxidation of thiamine alkyl disulfides with hydrogen peroxide in acetic acid solution or with perbenzoic acid in chloroform solution results in the formation of a sulfoxide of thiamine alkyl disulfides and this sulfoxide reacts with alkanethiol to form thiamine alkyl disulfides. Oxidation of thiamine benzyl sulfide with hydrogen peroxide in glacial acetic acid gave the sulfoxide of m. p. 133-134° (decomp.).
