Abstract: This thesis work investigated the reduction of carbonyl compounds to corresponding alcohols. The reduction was achieved via a catalytic transfer hydrogenation process using formic acid/formate as hydrogen source. The reduction of aromatic and aliphatic aldehydes was facile and occurred with 100 % yield over the Ru/AlO(OH) catalyst. In comparison, ketones were less readily reduced although moderate to excellent yield could be obtained after a longer reaction time. The unsaturated carbonyl compounds were successfully reduced to corresponding allylic alcohols over the amine-modified Ru/AlO(OH). Different amines were studied and the optimum amine was determined to be 3-(2-aminoethylamino)propyltrimethoxysilane. High yields of allylic alcohols, > 95 %, were obtained. The improvement in chemoselectivity to carbonyl groups was attributed to an increase in electron density at the Ru atom upon coordination with the amino groups.
