Abstract: In order to develop a new and facile route to the syntheses of thiocarbamates, selenium-mediated carbonylation of aniline with thiols was studied. Mediated by selenium, aniline reacted readily with carbon monooxide and thiols to afford thiocarbamates under the conditions of ambient temperature and atmospheric pressure. The results show that the reaction can proceed well to thiocarbamates in high yields with less hindered alkyl thiols. Selenium could be easily recovered and recycled.

Key words: Selenium, Aniline, Thiol, Carbonylation, Thiocarbamate
