Catalytic reduction of aromatic ketones is an interesting reaction that leads to the obtaining of alco-hols. Some of these alcohols are employed as intermediaries to produce chemical fine compounds. Thebimetallic catalysts are widely used in the chemoselective hydrogenation. The Surface OrganometallicChemistry on Metals (SOMC/M) is a methodology employed to obtain bimetallic systems.In the present work the hydrogenation of ketones derived from acetophenone has been studied. Theaim was observe the effect on activity and selectivity to aromatic alcohols by the presence of substituentsin the ring. The chemical characteristics of substituents groups could influence the way aromatic ketonesare absorbed on the metallic surface. This fact can be explained by a combination of geometric andelectronic effects.
