Abstract The reaction of thiocarbamates with sodium hydrogen selenide in ethanol led to the cleavage of both C-N and C-S bonds in thiocarbamates, which afforded the corresponding amines and thiophenols or thioalcohols in good yields. To the best of our knowledge, this provides a new reaction of thiocarbamates. A plausible mechanism has been proposed.
