New Strategy for Enantioselective Heterogeneous Catalysis: Immobilization of both Metal Nanoparticles and Chiral Modifiers on Mesoporous Silica Nanoparticles

Are you a silican or a silican′t?By using a cocondensation method, well defined rhodium nanoparticles and chiral reagent (−)‐cinchonidine were immobilized and stabilized on mesoporous silica nanoparticle surface simultaneously. For the enantioselective hydrogenation of ethyl pyruvate, the enantioselectivity was very well preserved during the catalyst recycling without any additional chiral reagent supplement.
