Abstract
Benzyl p-toluenethiosulfonate was found to form dibenzyltrisulfide with amine catalyst in the presence of water. On the other hand, α-benzylmercaptobenzyl p-toluenethiosulfonate was formed with amine catalyst in the presence of sulfur in 15% yield, without any dibenzyltrisulfide was obtained. The treatment with sodium hydroxide solution also gave benzylmercaptobenzyl p-toluenethiosulfonate in 49% yield. The mechanism of these reaction was presumed.
