Abstract

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 sp² 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.
