Palladium-Catalyzed Regioselective C-H Bond ortho-Acetylation and Oxidative Homocoupling of N-Arylcarbamates

摘要

An efficient and straightforward protocol for the regioselective acyloxylation of N-arylarbamates via Pd-catalyzed C-H bond functionalization has been demonstrated.The aliphatic and benzoic acid derivatives were used as the acyloxyl source to convert aromatic sp~2 C-H bonds into C-O bonds.Additionally,the oxidative homocoupling of N-arylarbamates were evaluated and gave the corresponding homocoupled products in good yields.
