Mechanistic Studies in the Chemistry of Thiourea. Part 1. Reaction with Benzil Under Alkaline Conditions

Benzil reacts under alkaline conditions with 1,3-dimethylthiourea to form 4,5-dihydroxy-1,3-dimethyl-4,5-diphenyltetrahydroimidazole-2-thione (1); with 1-methylthiourea to form 3-methyl-5,5-diphenyl-2-thiohydantoin (9); and with thiourea to form both the corresponding hydantoin and 3a,7a-diphenyltetrahydroimidazoimidazole-2,5-dithione (19).The use of high field n. m. r. spectroscopy and benzil labelled with carbon-13 in the carbonyl group has permitted delineation of the reaction mechanisms and detection of a number of transient intermediates.
