The reduction of different types of aldehydes and ketones
were performed in the presence of isopropylalcohol (as solvent
and hydride source) under microwave irradiation. It is
proved that dehydrated Woelm chromatographic alumina
supported KOH catalyses these transformations. Regioselectivity
was observed in the reduction of cinnamaldehyde
and chemoselectivity was observed in the reduction
of carbonyl in the presence of nitro group.
