Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>Al₂O₃ or SiO₂ particles with abundant surface hydroxyl groups can prevent side reactions of aromatic compounds with AlCl₃ completely; this Lewis acid can potentially destroy the stable structure of aromatic compounds to a large extent. This discovery was successfully utilized in the highly efficient hydrogenation of benzene, toluene, and naphthalene under mild conditions co‐catalyzed by AlCl₃ and Pd/Al₂O₃ or Pd/SiO₂. Pd, AlCl₃, and the surface hydroxyl groups on the support show excellent cooperative effects for the hydrogenation reactions. Theoretical studies indicate that formation of a complex, by an interaction between benzene, AlCl₃, and the solid oxides, plays a key role in the highly efficient hydrogenation reactions.</p> </abstract>
