A Facile Conversion of Amides and Lactams to Thioamides and Thiolactams using Tetrathiomolybdate

Chloro iminium salts generated in situ from amides and lactams using (COCl)2 or POCl3 reacted very readily with the new sulfur transfer reagent, benzyltriethylammonium tetrathiomolybdate to afford the corresponding thioamides and thiolactams in excellent yields under mild reaction conditions.
