Rh‐Catalyzed Direct Amination of Unactivated C(sp³)−H bond with Anthranils Under Mild Conditions

Abstract

C-N Bond formation is of great significance due to the ubiquity of nitrogen-containing compounds. Here, a mild and efficient Rh(III) -catalyzed C(sp(3) )-H aryl amination reaction is reported. Anthranil is employed as the nitrogen source with 100 % atom efficiency. This C-H amination reaction exhibits broad substrate scope without using any external oxidants. Mechanistic studies including rhodacycle intermediates, H-D exchange, kinetic isotope effect (KIE) experiments, and in situ IR are presented.
