摘要： 用强碱性阴离子交换树脂制备了硼氢阴离子交换树脂还原剂(BER),使其在氯化铜等金属化合物的催化下还原一些芳香硝基、氰基、氮氮双键等含氮功能基化合物.还研究了BER的制备条件:如温度、溶剂、不同金属化合物对还原反应的影响,并初步探讨其反应机理.

Abstract: Borohydride exchange resin (BER) was synthesized by a commercial macroporous strong basic anion exchange resin.Some nitrogenous functional groups, such as nitro, cyano and diazo compounds were reduced by using this polymeric reducing agent under the catalysis of some metal compounds, such as CuCl2, CoCl2 and NiCl2, respectively.The effects of the reaction temperature and solvents, etc.on reducing reaction were also investigated.The reducing reaction mechanism was proposed.It is found that BER-CuCl2/EtOHsystem was effective for reducing nitro, cyano and diazo compounds.

Key words: Borohydride exchange resin (BER), Polymeric reducing agent, Polymer-supported reagent, Metal boride
