Abstract

Reaction of N,N’-thionyldiimidazole with thiols effects the formation of disulfides and trisulfides. These results are rationalized by assuming that the thiols react with N,N’-thionyldiimidazole to produce the disulfides and N,N’-thiobisimidazole which subsequently reacts with the starting thiols to give the trisulfides.
