Abstract

The new spherical sol-gel hybrid material SiliaCat Pd⁰ selectively mediates the hydrogenolysis of aromatic alcohols, aldehydes, and ketones by using an ultralow catalytic amount (0.1 mol % Pd) under mild reaction conditions. The broad reaction scope as well as the catalyst's superior activity and pronounced stability open the route to green and convenient reductive deoxygenation processes of primary synthetic relevance in chemical research as well as in the fine chemical and petrochemical industries.

Keywords: hydrogenolysis; organically modified silica; palladium; sol–gel; sphericity.
