Abstract

The invention comprises a reagent for effecting reduction of organic compounds comprising a quaternary ammonium borohydride having the formula Rx(CH3)yNBH4 where R is a saturated or unsaturated straight chain aliphatic hydrocarbon radical containing from 7 to 21 carbon atoms and x and y are integers from 1 to 3 and x+y equals 4, in solution in an inert liquid hydrocarbon, such as benzene, hexane, ligroin or mineral oil. The quaternary ammonium borohydride may be made by adding a solution of the quaternary ammonium chloride in isopropanol to a methanolic solution of sodium borohydride and sodium hydroxide, filtering off sodium chloride and removing solvents by vacuum distillation. The above reagent may be used to reduce an organic compound having a reducible functional group e.g. an aldehyde, ketone, acid halide or organic peroxide at a temperature sufficient to cause reduction but low enough to avoid thermal decomposition of the borohydride. Examples describe the reduction of p-hydroxybenzaldehyde to p-hydroxybenzyl alcohol; 2 ethyl hexaldehyde to 2-ethylhexanol; p-nitrobenzoyl chloride to p-nitrobenzyl alcohol; benzoyl peroxide to benzoyl anhydride; ethyl p-nitrobenzoate to p-nitrobenzyl alcohol; and benzoyl chloride to benzyl alcohol.
