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.

practical meta C–H chlorination protocol is established via a Ru(0)-catalyzed ortho-metalation strategy. The use of N-chloro-2,10-camphorsultam as a newchlorinating agent is crucial for the success of the current reaction and an N-heterocyclic carbene (NHC) ligand could significantly enhance the reactivity of the catalytic transformation. The mechanistic studies reveal that an unusual ortho C–H ruthenation
