摘　　要：A series of novel Schiff bases bearing triazole structure were synthesized and characterized by LR and NMR. Mn（OAc）2/Schiff base efficiently catalyzed Henry reaction of nitroalkanes with aldehydes to produce the corresponding products of ^-nitroalcohols, under mild conditions with high yields （up to 99%）. A reaction mechanism is proposed based on the experimental results.A series of novel Schiff bases bearing triazole structure were synthesized and characterized by LR and NMR.
