Palladium-Catalyzed Oxidative Carbonylation of Aromatic C–H Bonds of N-Alkylanilines with CO and Alcohols for the Synthesis of o-Aminobenzoates
摘要:
A Pd(II)-catalyzed CH monocarbonylation of N-alkylanilines for the synthesis of o-aminobenzoates has been developed. Various aliphatic alcohols and phenol were tolerated in the reaction to afford the corresponding o-aminobenzoates in good yields under mild balloon pressure of CO.

The palladium/copper-catalyzed aerobic oxidative C-H carbonylation for the synthesis of o-aminobenzoates is described. Molecular oxygen is used as the terminal oxidant. This methodology proceeds with a wide range of N-substituted anilines and alcohols and gives straightforward access to valuable o-aminobenzoates.
