Mechanistic Studies in the Chemistry of Thiourea. Part 2. Reaction with Benzil in Acid Solution

Benzil reacts with 1,3-dimethylthiourea, 1-methylthiourea, and thiourea in acid solution to give 4,5-diphenyl-4-imidazolines (3) which, in the cases of 1-methylthiourea and thiourea, readily form disulphides 11.Another product of reaction is a bicyclic compound 4 in which it appears that in one thiourea moiety sulphur has been replaced by oxygen.A mechanistic pathway for the formation of 3 and 4 is proposed involving thioureas acting as sulphur nucleophile, urea as a leaving group, and the thermal decomposition of thiiranes.
