Abstract
Application of alkanethiol, alkyl alkanethiolsulfinate, or sodium alkylthiosulfate to thiamine disulfide (I) results in the formation of thiamine alkyl disulfide. The amount of thiamine alkyl disulfide formed from (I) and alkanethiol is barely detected by paper partition chromatography but the amount formed increases if (I) is preliminarily oxidized with hydrogen peroxide. In such a case, the formation of a sulfoxide, sulfodioxide (IX), and sulfenic acid derivative (X) of (I) can be assumed as intermediates
