    摘要： The invention relates to 1,2-ferrocenyldiphosphines which contain a functional group in the 1′ position either directly or via a bridging group, and also a process for their preparation. The compounds are important for transition metal complexes containing d-8 metals such as Rh, Ru, Pd or Ir. These transition metal complexes are widely used in the hydrogenation of organic double or triple bonds, in particular olefinic double bonds and carbon-heteroatom double bonds. The complexes are particularly suitable for enantioselective hydrogenation using chiral ferrocenyldiphosphines and corresponding prochiral unsaturated compounds. Ferrocenyldiphosphines having a functional group in the 1′ position are also important intermediates for ferrocenyldiphosphine ligands and their metal complexes of d-8 metals such as rhodium, ruthenium, palladium or iridium which are bound to inorganic polymeric supports via this functional group. These metal complexes bound to an inorganic or organic support material are likewise very suitable for the hydrogenation of organic double or triple bonds.

    摘要翻译： 本发明涉及直接或通过桥连基团在1'位置含有官能团的1,2-二茂铁基二膦，以及它们的制备方法。 该化合物对于含有d-8金属如Rh，Ru，Pd或Ir的过渡金属络合物是重要的。 这些过渡金属络合物广泛用于有机双键或三键的氢化，特别是烯属双键和碳 - 杂原子双键。 配合物特别适用于使用手性二茂铁二膦和相应的前手性不饱和化合物的对映选择性氢化。 在1'位置具有官能团的二茂铁基二膦也是二茂铁基二膦配体及其金属络合物的重要中间体，其中d-8金属如铑，钌，钯或铱通过该官能团与无机聚合物载体结合。 与无机或有机载体材料结合的这些金属络合物同样非常适用于有机双键或三键的氢化。
