Reaction of the sodium salt of thiamine and phenylmethanesulfonyl chloride affords, besides thiamine disulfide, a minute amount of two kinds of crystals of m. p. 201°(decomp.) and 148°(decomp.). The structures of these substances were assumed from infrared absorption spectra and others to be O, O′-diphenylmethanesulfonylthiamine disulfide (V) for that of m. p. 201°(decomp.) and O-phenylmethane-sulfonylthiamine disulfide (VI) for that of m. p. 148°(decomp.), and they were confirmed by syntheses.
