    Project supported by the National Natural Science Foundation of China (No. 21462031), the Initial Special Research for National Basic Research Program of China (No. 2014CB460609) and the Research Program of Science and Technology at University of Inner Mongolia Autonomous Region (No. NJZZ14032).

Catalyzed by supported palladium nanoparticles, an aminolysis reaction between various aryl esters and quaternary ammonium salts via twice C-N bond activations has been developed for selectively synthesis of amides. The Pd/γ-Al2O3 catalyst exhibited an excellent catalytic activity and reusability of at least five recycles in air for the reaction. The experiment results indicated that the first C-N cleavage of quaternary ammonium salt affords the tertiary amine and halohydrocarbon, and the second C-N cleavage proceeds via the formation of an iminium intermediate.

Key words: quaternary ammonium salts, aminolysis, palladium, C-N activation, aryl esters
