A Novel One-Pot Solvent-Free, Triethylamine-Assisted, SeleniumCatalyzed 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.
