Selective Reduction of Carbonyl Compounds Using Two Phase Reduction with Sodium Borohydride

[摘要] Approximate rate and stoichiometry of the reaction of ten compounds which contain functional group such as nitrile, nitro, halogen and one of these functional group together with a carbonyl group by the two phase reduction were tested at room temperature. Nitrile, nitro and halogen were all inert under these condition. Therefore selective reduction of carbonyl group in the presence of these group were examined. Thus m-nitrobenzaldehyde, m-nitroacetophenone, p-bromoacetophenone and p-cyanobenzaldehyde were reduced to corresponding alcohols in excellent yields, 95¡­100 %.
