The reaction of organolithium derivatives with thiuram monosulfides gives a convenient method for the synthesis of both aromatic and aliphatic thioamides in good yields. In our hands, the reaction of organolithium derivatives with tetramethylthiuram disulfide gave only dithiocarbamates and not a mixture of these and thioamides.

An efficient protocol for the copper-catalyzed preparation of aryl dithiocarbamates from aryl iodides and inexpensive, environmentally benign tetraalkylthiuram disulfides was developed. The features of mild reaction conditions, high yields, and broad substrate scope render this new approach synthetically attractive for the preparation of potentially biologically active compounds.
