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.

A mild and efficient Mitsunobu-based protocol has been developed for the
synthesis of various S-alkyl thiocarbamates from the corresponding thiols
and amines using gaseous carbon dioxide, in good to excellent yields.

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.

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.

A mild, convenient, and practical one-pot procedure gives dithiocarbamates in
good to excellent yields by condensation of amines, CS2, and a
Michael acceptor, under solvent-free conditions at room temperature.
