Synthesis of novel aryl and heteroaryl acyl sulfonimidamides via Pd-catalyzed carbonylation using a nongaseous precursor.

Hitherto unexplored aryl and heteroaryl acyl sulfonimidamides have been prepared through the development of a new Pd-catalyzed carbonylation protocol. This novel methodology, employing sulfonimidamides as nucleophiles and CO gas ex situ released from solid Mo(CO)6 in a sealed two-chamber system, yields a wide range of carbamate protected acyl sulfonimidamides in good to excellent yields.
