| 英文摘要 | the nanocomposites formed by so3h-hollow-nanospheres and chiral amines are highly efficient catalysts for the direct asymmetric aldol reaction of cyclohexanone and 4-nitrobenzaldehyde. the catalyst showed 91% yield with 96% ee under optimized reaction conditions. so3h-hollow-nanospheres were synthesized by oxidation of thiol-hollow-nanospheres, which were fabricated through a one-pot co-condensation of 1,2-bis(trimethoxysilyl) ethane and 3-mercaptopropyltrimethoxysilane around f127 micelles in the presence of naoac. chiral amines could be combined with so3h-hollow-nanospheres through facile electrostatic interactions. the obtained nanocomposites showed a much higher reaction rate than the catalyst formed from the combination of chiral amine and so3h-mesoporous-organosilica (ribbon shaped particles with particle size of tens of micrometres) in the direct asymmetric aldol reaction. this is mainly attributed to the hollow spherical morphology and nano-scale particle size (16-20 nm) of the so3h-hollow-nanospheres. |
