Visible-Light-Enabled Construction of Thiocarbamates from Isocyanides, Thiols, and Water at Room Temperature.

A convenient visible-light-induced method for the synthesis of thiocarbamates from isocyanides, thiols, and water has been developed under mild reaction conditions. The present protocol offers a cost-effective and operationally straightforward approach to the various thiocarbamates in moderate to good yields by simple use of cheap Rose Bengal as the photocatalyst and water as the reaction reagent as well as an environmentally benign cosolvent.
