    • Chiral compounds of the formula (1 ), which are optically pure or highly optically enriched in which R 0 is C 1 -C 12 -alkyl which is unsubstituted or substituted by 1 to 2 C 1 -C 4 -alkoxy; cyclo- pentyl or cyclohexyl, which is unsubstituted or substituted by 1 to 3 C 1 -C 4 -alkyl or C 1 -C 4 -alkoxy; or benzyl, phenyl or naphtyl which is unsubstituted or substituted by 1 to 3 C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy, C 1 -C 4 -fluoroalkyl or C 1 -C 4 -fluoroalkoxy, F or Cl, or R 0 is -C R 5 R 6 OH or -C R 5 R 6 OSi(C 1 -C 8 -alkyl) 3 wherein R 5 and R 6 are indedendently selected from the group consisting of H, unsubstituted C 1 - C 12 alkyl, substituted C 1 - C 12 alkyl, unsubstituted C 4 - C 8 cyclo alkyl, substituted C 4 - C 8 cyclo alkyl, unsubstituted aryl, substituted aryl or wherein R 5 and R 6 can form an unsubstituted 5-6 membered aliphatic carbocycle or a substituted 5-6 membered aliphatic carbocycle, each of R 1 and R' 1 independently is hydrogen or has the meaning of R 0 whereby R 1 , R' 1 and R 0 can be same or different, R 2 and R 3 are independently a C-bonded hydrocarbon radical or a heterohydrocarbon radical, and each of both R 4 is C 1 -C 6 -alkyl, cyclopentyl, cyclohexyl, phenyl, methylphenyl, methylbenzyl or benzyl, or both R 4 together form an aliphatic C 4 -C 6 carbocycle. Metal complexes of these ligands are homogeneous catalysts for asymmetric addition reaction, particularly hydrogenations.
    • 式(1)的手性化合物,其是光学纯的或高度光学富集的,其中R 0是未被取代或被1至2个C 1 -C 4 - 烷氧基取代的C 1 -C 12 - 烷基; 未取代或被1至3个C 1 -C 4 - 烷基或C 1 -C 4 - 烷氧基取代的环戊基或环己基; 或未被取代或被1至3个C 1 -C 4 - 烷基,C 1 -C 4 - 烷氧基,C 1 -C 4 - 氟烷基或C 1 -C 4 - 氟烷氧基,F或Cl或R 10取代的苄基,苯基或萘基, OH或-C R5 R6 OSi(C1-C8-烷基)3,其中R5和R6独立地选自H,未取代的C1-C12烷基,取代的C1-C12烷基,未取代的C4-C8环烷基,取代的C4 -C 8环烷基,未取代的芳基,取代的芳基或其中R 5和R 6可以形成未取代的5-6元脂族碳环或取代的5-6元脂族碳环,R 1和R'1各自独立地是氢或具有 R 0,其中R 1,R'1和R 0可以相同或不同,R 2和R 3独立地是C键合的烃基或杂烃基,并且R 2各自为C 1 -C 6 - 烷基,环戊基,环己基,苯基,甲基苯基 ,甲基苄基或苄基,或两者一起形成脂族C 4 -C 6碳环。 这些配体的金属络合物是用于不对称加成反应,特别是氢化的均相催化剂。
