Rhodium(iii)-catalyzed aromatic C–H cyanation with dimethylmalononitrile as a cyanating agent

Abstract

A rhodium-catalyzed aromatic C–H bond direct cyanation with safe, bench-stable, and commercially available dimethylmalononitrile as the cyanating agent has been successfully developed by using copper oxide as a promotor. Pyridine, quinoline, pyrimidine and pyrazole were used as the directing group in this type of C–H bond direct cyanation reaction.
