Copper Catalyzed C–N Cross-Coupling Reaction of Aryl Boronic Acids at Room Temperature through Chelation Assistance
2017
A copper-catalyzed selective C–N cross-coupling has been developed based on chelation-assisted amidation of readily available aryl boronic acids at room-temperature under open-flask conditions. The reaction is scalable and tolerates a wide spectrum of functional groups delivering fully substituted unsymmetrical amides in high yields (up to 96%). The C–N cross coupling also established with aryl silanes, extending the palette of coupling partners of this strategy.
