Studies on the Reduction of Aromatic Oximes Using Borohydride Exchange Resin-Nickel Boride (cat.)

Abstract

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
