A mild and efficient copper-catalyzed N-arylation of unprotected sulfonimidamides using boronic acids

摘要

An efficient and low cost copper catalyzed system for N-arylation of sulfonimidamides has been developed. The reaction proceeds at room temperature under base free conditions. Various N-aryl, N-hetero-aryl, and N-cyclopropyl sulfonimidamides were obtained in good to excellent yields.
