Matsukawa and others detected the formation of thiothiamine during air oxidation of aqueous solution of free thiamine but later, Zima and others showed that these reactions were instituted by hydrogen sulfide on thiamine and that air oxidation was unnecessary. Reëxamination of Zima's experiments was carried out with examination of various sources for sulfur supply anticipated in this reaction, and it was confirmed that the substance responsible for this reaction is sulfur itself. It is assumed that this sulfur is formed by the oxidation of hydrogen sulfide which is produced by the decomposition of thiamine and that air is required in this reaction.
