  摘要：

  The commercially available ferrocene-based diphosphine ligand (S-c,S-Fc)-TaniaPhos was found to be highly effective in the Rh-catalyzed asymmetric hydrogenation of 3-aryl-2-(phosphonomethyl)propenates. Excellent enantioselectivity (90-98% ee) and high catalytic activity (S/C up to 1000) have been achieved, which represents the best results reported so far. (C) 2011 Elsevier Ltd.

  A new class of chiral ferrocenyl diphosphine ligands with an imidazole ring, (Rc,SFc)-ImiFerroPhos, has been prepared from acylferrocenes through a five-step transformation and successfully applied in the Rh-catalyzed asymmetric hydrogenation of various 3-aryl-substituted 2-phosphonomethylpropenoates, in which a series of chiral 3-phosphono-2-arylmethylpropanoic acid derivatives were achieved in ee

  新型的具有咪唑环的手性二茂铁基二膦配体（R c，S Fc）-ImiFerroPhos通过五步转化由酰基二茂铁制备，并成功地用于Rh催化的各种3-芳基-不对称加氢反应取代的2-膦酰基甲基丙酸酯，其中一系列手性3-膦酰基-2-芳基甲基丙酸衍生物的ee值高达98％。
