Copper oxide supported on silica by the Chemisorption–Hydrolysis technique shows a moderate Lewis acidic character due to coordinative unsaturation of the finely dispersed supported metallic phase. Comparison of this material with a conventional acidic catalyst, namely SiO2–Al2O3, puts in light the advantages of this kind of acidic material in three different reactions. Thus, the use of CuO/SiO2 boosts...
