Compounds of the formulae (I) and (Ia) where X
1
is secondary phosphino; R
3
is a hydrocarbon radical having from 1 to 20 C atoms, a heterohydrocarbon radical which has from 2 to 20 atoms and at least one heteroatorn selected from the group consisting of O, S, NH and NR, or an —SO
2
—R radical; R is C
1
-C
18
-alkyl, phenyl or benzyl; the radicals R
4
are each, or the two radicals R4 together a hydrocarbon radical having from 1 to 20 C atoms; R
01
is a hydrocarbon radical having from 1 to 20 C atoms; and R
02
and R′
o2
are each, independently of one another, a hydrogen atom or independently have the meaning of R
01
, or R
01
and R
02
together with the C atom to which they are bound form a three- to eight-membered hydrocarbon or hetero hydrocarbon ring. The compounds are chiral ligands for complexes of metals of transition groups I and VIII which act as catalysts for asymmetric additions, for example of hydrogen, onto prochiral unsaturated organic compounds.
化合物的公式(I)和(Ia),其中X1是二级膦基;R3是具有1至20个C原子的碳氢基团,具有2至20个原子并且至少有一个杂原子(选自O,S,NH和NR的群体)的杂碳氢基团,或者是一个—SO2—R基团;R是C1-C18-烷基,苯基或苄基;基团R4是每个,或两个基团R4共同形成具有1至20个C原子的碳氢基团;R01是具有1至20个C原子的碳氢基团;R02和R'o2各自独立地是氢原子,或者独立地具有R01的含义,或者R01和R02与它们所连接的C原子一起形成一个三至八元环的碳氢或杂环碳氢基团。这些化合物是过渡金属I和VIII族的配合物的手性配体,可作为催化剂用于对不对称不饱和有机化合物的加成反应,例如氢的加成反应。
