报道了一种纳米金催化(杂环)芳基酯与卤代烷经由C-O键活化的酯交换反应.在一系列负载金纳米颗粒和钯纳米颗粒催化剂中,粒径为3.63 nm,负载量为3 wt%的Au/γ-Al2O3催化剂表现出最佳催化活性.该催化剂重复使用五次后仍表现出较高活性.对反应前后催化剂的X射线光电子能谱(XPS)分析表明,该反应可能是通过以Au0为始态的催化循环来进行的.

关键词: 纳米金催化剂, 酯交换反应, 卤代烷

Nano-gold catalyzed transesterification of the (hetero) aryl ester with alkyl halides via C-O activation has been developed. In a series of supported AuNPs and PdNPs, the Au/γ-Al2O3 catalyst with an AuNP mean diameter of 3.63 nm and 3 wt% Au loading exhibited the best catalytic performance. The catalyst can be reused and shows high activity after five cycles. The X-ray photoelectron spectroscopy (XPS) analysis of the catalyst before and after the reaction suggested that the reaction might be performed via a catalytic cycle that began with Au0.

Key words: nano-gold catalyst, transesterification, halide
