Abstract

N,S-Divinyl-2-mercaptobenzimidazole reacts with thiols under free-radical initiation conditions at both vinyl groups to give β-addition products, whereas it reacts with sulfur dioxide to give a stable complex. N-Vinylbenzimidazole-2-thione was obtained by heating the divinyl derivative of benzimidazole-2-thione in the presence of a mercaptan without a catalyst. The former on reaction with thiols under the influence of azobisisobutyronitrile readily forms N-(β-alkylthio)ethylbenzimidazole-2-thiones; in the presence of ionic catalysts, N-(α-alkylthio)ethylbenzimidazole-2-thiones are formed.
