用于不对称氢化反应中的二(二茂铁基膦)二茂铁配体
摘要：
呈外消旋化合物、对映体纯的非对映体或非对映体混合物形式的式I化合物，其中基团R1相同或不同，并且各自是C1－C4－烷基；m是0或1－4的整数；n是0或1－3的整数；p是0或1－5的整数；R2是芳香烃基团或C－键合的杂烃基团，并且R3是脂肪族或C－键合的杂脂肪族烃基团；R2和R3相同或不同，并且各自是脂肪族或C－键合的杂脂肪族烃基团；R4是未取代或C1－C6－烷基－、C1－C6－烷氧基－或卤素－取代的烃基团；并且A是仲氨基团，其是金属配合物的配体，所述金属配合物适于作为均相对映体选择性加氢的催化剂。
摘要（英）：

Abstract Compounds of the formula (I) in the form of racemates, enantiomerically pure diastereomers or a mixture of diastereomers, where the radicals R1 are identical or different and are each C1-C4-alkyl; m is 0 or an integer from 1 to 4; n is 0 or an integer from 1 to 3; p is 0 or an integer from 1 to 5; R2 is an aromatic hydrocarbon radical or a C-bonded heterohydrocarbon radical and R3 is an aliphatic or C-bonded heteroaliphatic hydrocarbon radical; R2 and R3 are identical or different and are each an aliphatic or C-bonded heteroaliphatic hydrocarbon radical; R4 is an unsubstituted or C1-C6-alkyl-, C1-C6-alkoxy-or halogen-substituted hydrocarbon radical; and A is a secondary amino group, are ligands for metal complexes which are suitable as catalysts for homogeneous enantioselective hydrogenation.
