Synthesis of thiocarbamates and related compounds

Recent Literature

S-Alkyl thiocarbamates and S-alkyl O-alkyl carbonothioates were synthesized in good yields by solvent-assisted thiocarboxylation of amines or alcohols with carbon monoxide and sulfur under mild conditions (1 atm, 20 °C) in DMSO or DMF.

Readily prepared carbamoylimidazolium salts act as efficient N,N-disubstituted carbamoylating reagents, as a result of the ‘imidazolium’ effect. The salts react with amines, thiols, phenols/alcohols, and carboxylic acids in high yields, without the need for subsequent chromatographic purification of the products, producing ureas, thiocarbamates, carbamates, and amides, respectively.

Related A highly efficient, mild and simple synthesis of dithiocarbamates is based on the one-pot reaction of amines, CS2, and alkyl halides without using a catalyst under solvent-free conditions. The reaction is a highly atom-economic process for production of S-alkyl thiocarbamates. N. Azizi, F. Aryanasab, M. R. Saidi, Org. Lett., 2006, 8, 5275-5277.
