    Notes: Reductive Displacement of the Acetate Group in Allyl, Propargyl, and Benzyl Acetates by NaBH4/NiCl2 · 6 H2OThe combination of NiCl2 · 6 H2O and NaBH4 provides an effective system for reductive removal of the acetate group of allyl, propargyl, and benzyl acetates. Sterically less hindered allyl acetates are converted preferentially to the corresponding alkanes (Table 1).

    Reduktion von Oximen mit Natriumboranat in Gegenwart von Übergangsmetallverbindungen (1984)

    Notes: Reduction of Oximes with Sodium Borohydride in the Presence of Transition Metal CompoundsThe 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.

    Notes: Reaction of Diphenylcyclopropenone with AllylidenetriphenylphosphoranesAllylidenetriphenylphosphoranes 2 react with diphenylcyclopropenone (1) via a ring opening mechanism. While reaction of 2a and 2b yields the bicyclic phosphane 3 through the zwitterion 4 as intermediate, two equivalents of 2c react with 1 to produce the allene 10.
