Cobalt(III)-Catalyzed C–H Amidation of Arenes using Acetoxycarbamates as Convenient Amino Sources under Mild Conditions
摘要:
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.
