phosphite-type ligands derived from readily available ferrocene-based iminoalcohols were successfully used in Rh-catalysed hydrogenations and Pd-catalysed allylic substitutions of a variety of substrates. Moderate-to-high catalytic activities under standard conditions were observed, and the enantiomeric excess of the products were up to 97 %. Results obtained under systematic variation of the ligand parameters
几种源自易于获得的二茂铁基亚氨基醇的 N,P 二齿亚磷酸酯型配体已成功用于各种底物的 Rh 催化氢化和 Pd 催化的烯丙基取代。在标准条件下观察到中到高的催化活性,产物的对映体过量高达 97%。在配体参数的系统变化下获得的结果表明,对映选择性主要由磷酸中心的性质以及 C*HN 片段中的取代基决定。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
