Cobalt(III)-catalyzed C-H amidation of arenes using acetoxycarbamates as convenient amino sources under mild conditions

Abstract

The Co(III)-catalyzed direct C−H amidation of arenes has been developed using O-acylcarbamates as a convenient amino source. This reaction proceeded in high efficiency under external oxidant-free conditions with a broad range of arene substrates, including 6-arylpurines bearing sensitive functional groups, thus furnishing synthetically versatile arene N-carbamate products.
