Published 1984 · Chemistry
Reduction of Oximes with Sodium Borohydride in the Presence of Transition Metal Compounds The reduction of oximes with sodium borohydride in the presence of NiCl2 · 6 H2O and MoO3 was investigated. The combination of NaBH4 with NiCl2 · 6 H2O converted the unsaturated oximes through exhaustive reduction into saturated amines (Table 1). The C = C double bond remains preserved if the reduction is carried out in the presence of MoO3 (Table 2). The stereo-chemistry of the reduction in the presence of NiCl2 · 6 H2O is distinctivly different from that of MoO3.
