摘要: Mesoprous ethane-silicas with trans-(1R,2R)-diamninocyclohexane bridged in the framework were synthesized by one-step co-condensation under basic/acid conditions. These novel materials (complexed with [Rh(cod)Cl]2) are efficient catalysts for the asymmetric transfer hydrogenation of acetophenone. Compared with pure mesoporous silica counterparts, these chiral ethane-silicas are twice more active, which could be contributed to the increased hydrophobicity of the mesoporous ethane-silicas. Tuning the mesophase of the material from MCM-41 to SBA-15 can further improve the catalytic activity of the resulting catalyst. Adjusting the linker of the chiral ligand from propyl group to benzyl group can boost the catalytic activity and chiral inductivity of the materials. Key words: Periodic Mesoporous Organosilicas, Chirality, trans-(1R,2R)-Diaminocyclohexane
