S. Yakabe et al., SIMPLE REDUCTION OF VARIOUS KETONES WITH SODIUM TETRAHYDROBORATE AND ALUMINA IN HEXANE, Journal of chemical research. Synopses (Print), (6), 1998, pp. 322
A combination of NaBH4 and alumina preloaded with a small amount of wa
ter is a highly efficient reducing agent for cycloalkanones, substitut
ed cyclohexanones and unsaturated and aromatic ketones in hexane, affo
rding the corresponding alcohols in excellent yields under mild condit
ions (20-60 degrees C).
