摘要/Abstract
合成了一种手性1,1'-联萘-2,2'-二苯膦(BINAP)功能化的多孔有机聚合物,用碳固体核磁谱(13C CP/MAS NMR)、磷固体核磁谱(31P CP/MAS NMR)、傅里叶变换红外光谱(FT-IR)、粉末X射线衍射(PXRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、氮气吸附和热重分析(TG)对材料进行表征,这个材料具有无定型的微孔结构.与Ru(Ⅱ)络合后,复合材料Ru/POP-BINAP可非均相催化β-酮酸酯的不对称氢化,并表现出优良的催化活性、对映选择性和循环性.

A porous organic polymer (POP) with chiral 2,2'-bis(diphenylphosphino)-1,1'-binaphthalene (BINAP) has been prepared and characterized by several techniques including 13C CP/MAS NMR, 31P CP/MAS NMR, fourier transform infrared spectroscopy, powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy and nitrogen adsorption. The material exhibits amorphous microporous structure. After loading of ruthenium(Ⅱ) species via coordination, the composite material Ru/POP-BINAP could be used as a heterogeneous catalyst for the asymmetric hydrogenation of β-keto esters with high activity, excellent enantioselectivity and recyclability.
Key words: porous organic polymer, heterogeneous catalysis, asymmetric hydrogenation, β-keto esters
