摘要：

Vapor-phase N-alkylation syntheses of imidazole were carried out with MeOH and EtOH over a series of calcined Mg-II-Al-III layered double hydroxides (LDHs) selectively produced in high yields of N-methyl (70%) and N-ethyl (63%) imidazoles only on the 3 : 1 atomic ratio of Mg-II-Al-III calcined LDH. Attempts on C-alkylation and dialkylation reactions over the same catalysts proved to be unsuccessful.
