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.

An improved method for the selenium-catalysed synthesis of thiocarbamates under mild conditions has been developed. With acetone as solvent, the one-pot selenium-catalysed carbonylation of nitroarenes and thiols with carbon monoxide proceeds smoothly at atmosphericpressure and ambient temperature.
