Selective Rhodium-Catalyzed C-H Amidation of Azobenzenes with Dioxazolones under Mild Conditions

摘要

A synthetic method for a wide range of amidated azobenzenes is developed from the selective rhodium-catalyzed C-H amidation reaction of symmetrical as well as unsymmetrical azobenzenes with alkyl-, aryl-, and heteroaryl-substituted dioxazolones under mild conditions. Diamidation of azobenzenes and amidation of monoamidated azobenzenes were also demonstrated.
