Reactions of a carbamoylstannane with acid chlorides: highly efficient synthesis of alpha-oxo amides.
Treatment of acid chlorides with a carbamoylstannane under mild conditions (mostly rt for a few hours) affords alpha-oxo amides in high yields. Vicinal polycarbonyl compounds are also obtained, although spontaneous decarbonylation occasionally occurs.
