A novel DBU-assisted carbonylation of amines with carbon monoxide and sulfur has been developed for the synthesis of S-alkyl thiocarbamates. In the presence of DBU (1, 8- diazabicyclo [5.4. 0] undec-7-ene), S-alkyl thiocarbamates are synthesized in excellent yields from amines, carbon monoxide, sulfur, and alkyl halides under mild conditions (1atm, 20° C). In the absence of DBU, however, no formation of S-alkyl thiocarbamate is ...
