Highly efficient double-carbonylation of amines to oxamides using gold nanoparticle catalysts

Hydrotalcite-supported gold nanoparticles (Au/HT) catalyzed the highly efficient double-carbonylation of amines to oxamides under mild reaction conditions. Various amines were selectively converted to the corresponding oxamides. The cooperation between gold nanoparticles and basic sites of HT plays a key role in the reaction.
