High active ligand usually plays an important role during catalysis and organic synthesis area. Unsymmetrical tridentate pyrazoly‐pyridinyl‐triazole ligand bridged copper composite supported on the ordered mesoporous material was synthesized from the designed ligand, simple copper salt and commercially available SBA‐15. The resulting copper composite was fully characterized by X‐ray photoelectron spectrometry, scanning electron microscopy and transmission electron microscopy and X‐ray power diffraction. Compared to traditional noble Ir, Ru, Rh and Pd complexes, this economical and stable heterogeneous copper revealed high catalytic selectivity for the reaction of hydronaphthalenones and alcohols with good recyclability. Mechanism explorations disclosed that oxidation, condensation and hydrogenation processes were all involved during this process and this provided an efficient method to the synthesis of 2‐benzyl‐3,4‐dihydronaphthalen‐1( 2H )‐onederivatives with good recyclability through the green borrowing hydrogen strategy.
