The reaction was found to proceed with ease even under mild conditions with very high yield in organic solvents under phase transfer catalysis method without the formation of any byproducts. The products, 1-phenyl ethanol and its para substituted derivatives were separated, purified, weighed and identified by infra-red spectral technique. The reaction under polar solvent is found to be very slow with low yield on comparison with the reaction in organic solvents under phase transfer catalysis condition. This reaction is also carried out in polar solvents like isopropyl alcohol so as to study the significance of phase transfer catalysis. Various phase transfer catalysts such as tetrabutylammonium bromide, tetrabutylammonium hydrogen sulphate, cetyltrimethylammonium bromide and tricaprylylmethylammonium chloride (Aliquat 336) were used. The selective reduction of acetophenone and its para substituted derivatives was carried out in organic solvents like ethyl acetate and toluene using sodium borohydride as reducing agent under phase transfer catalysis conditions.
