合成了具有立体和电子不对称结构的手性亚磷酸酯-膦配体,使用31P NMR和红外吸收光谱考察了其与金属铑(Ⅰ)离子的配位性能,并研究了得到的配合物对烯烃氢甲酰化反应的催化性能。获得了好的催化活性和区域选择性,但反应的对映选择性很低。
The chiral phosphite-phosphine ligands with stereosymmetric and electron-asymmetric structures were synthesized. Their coordination properties with rhodium (I) ions were investigated by using 31 P NMR and IR spectra. The effects of the complex pairs Catalytic Performance of Olefin Hydroformylation. Good catalytic activity and regioselectivity were obtained, but the enantioselectivity of the reaction was very low.
