摘要：

以氢硼化离子交换树脂为还原剂,甲醇作溶剂,加入催化量的醋酸镍,原位制备硼化镍催化剂的方法,还原芳香酮肟得到的产物为相应的α-取代苄胺,还原芳香醛肟得到的主要产物为双苄基仲胺,还原产物均经1HNMR, MS和元素分析确认.

Abstract:

Aromatic oximes were reduced with borohydride exchange resin (BER)-nickel acetate in methanol as efficient reducing system, the catalyst nickel boride(Ni2B) was formed in situ.The products of reduction of aromatic ketoximes were the corresponding α-substituted benzylamines, and the products of reduction of aromatic aldoximes were symmetric dibenzyl secondary amines, which was different to the result of reference.Their structures were confirmed by 1HNMR,MS and elemental analysis.

Key words: Aromatic aldoximes(ketoximes), Borohydride exchange resin(BER), Nickel boride, Reduction
