A novel one-pot solvent-free, triethylamine-assisted, selenium-catalyzed synthesis of thiocarbamates from nitroarenes, carbon monoxide, and thiols

A novel one-pot solvent-free synthesis of a series of thiocarbamates is reported. Nitroarenes, carbon monoxide, and thiols are the starting materials, with cheap element selenium as catalyst; this method offers a simple access to thiocarbamates mostly in moderate to good yields. The selenium catalyst can be easily recovered and recycled.
