Cobalt(III)-catalyzed C-H amidation of arenes using acetoxycarbamates as convenient amino sources under mild conditions
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, includin
N -substituted hydroxylamines as synthetically versatile amino sources in the iridium-catalyzed mild C-H amidation reaction
N-Substituted hydroxylamines such as aroyloxy- or acyloxycarbamates were successfully employed as synthetically versatile amino precursors in the iridium-catalyzed direct C-H amidation of arenes. The reaction proceeds smoothly at room temperature over a broad range of substrates with high functional group tolerance to afford N-substituted arylamine products.
