Studies on Antitumor Substances. X. Reactions of Thiosulfonates with Some Nucleophilic Compounds

Abstract

Reactivities of mono and difunctional thiosulfonates toward several nucleophilic compounds, such as thiols, amines and the related compounds, were examined. In the result, some chemical behaviors unexpected were found in addition to the reactivity anticipated. Namely, in the reaction with piperazine, aralkyl thiosulfonate afforded aralkyltrisulfide in about 20% yield, without any formation of sulfenamide. Moreover, aromatic thiosulfonate gave a comparable good yield of 1-phenyl-2-arylsulfonylhydrazine in the reaction with phenylhydrazine, in addition to the formation of phenylhydrazinium salt of aromatic sulfinic acid.
