报道了一种负载钯纳米颗粒催化多种芳基酯与季铵盐经由两次C-N键活化的,选择性合成酰胺的胺解反应.在这个反应中,Pd/γ-Al2O3催化剂表现出卓越的催化活性和空气中至少五次循环的重复利用性.试验结果表明季铵盐的第一次C-N键断裂得到卤代烷和三级胺,第二次C-N键断裂是通过产生亚胺离子中间体完成的.

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
