Mn(OAc)2/Schiff base as a new efficient catalyst system for the Henry reaction of nitroalkanes with aldehydes
摘要:
A series of novel Schiff bases bearing triazole structure were synthesized and characterized by IR and NMR. Mn(OAc)(2)/Schiff base efficiently catalyzed Henry reaction of nitroalkanes with aldehydes to produce the corresponding products of beta-nitroalcohols, under mild conditions with high yields (up to 99%). A reaction mechanism is proposed based on the experimental results. (C) 2012 Zheng Feng Xie. Published by Elsevier B.V. on behalf of Chinese Chemical Society. All rights reserved.
