complexes were used, the asymmetric hydroformylation of styrene gave 2- and 3-phenylpropanals with a substrate/catalyst ratio of 2000, iso/normal ratios of 84/16 to 89/11, and 89% R enantiomeric excess of 2-phenylpropanal; these results were at the highest level in catalytic activity, regio-, and enantioselectivities. Recovery-reuse of the catalyst was examined. Asymmetric hydroformylation of vinyl acetate
当使用聚合物固定的手性膦-亚磷酸酯-Rh(I) 配合物时,苯乙烯的不对称加氢甲酰化得到 2- 和 3-苯基丙醛,底物/催化剂比为 2000,异/正比为 84/16 至 89/11和 89% R 对映体过量的 2-苯基丙醛;这些结果在催化活性、区域选择性和对映选择性方面处于最高水平。检查了催化剂的回收再利用。乙酸乙烯酯、(Z)-2-丁烯和3,3,3-三氟丙烯的不对称加氢甲酰化也用聚合物负载的催化剂成功进行。
