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.

A new and facile route for the synthesis of thiocarbamates was reported. Mediated by selenium, aniline reacts very readily with carbonmonoxide and thiols in the presence of triethylamine, to afford the corresponding thiocarbamates mostly in moderate to excellent yields under mild reaction conditions. Selenium can be easily recovered and recycled.
