摘要

Silylated ferrocenyl-diphosphines (I) of formula (A; X = PR2R3), which are in the form of racemate and diastereomer (mixt.), are new: R1 = 1-8C alky; or phenyl, opt. mono- to tri-substd. by 1-4C alkyl or 1-4C alkoxy; R2,R3, R10, R11 = 1-12C alkyl; 5-12C cycloalkyl, opt. substd. by 1-4C alkyl or 1-4C alkoxy; or phenyl, opt. mono- to tri-substd. by 1-4C alkyl, 1-4C alkoxy, -SiR4R5R6, halogen, -SO2M, -CO2M, -PO3M, -NR7R8, -(+NR7R8R9)X- or 1-5C alkyl; or -PR2R3, -PR10R11 = a gp. of formula (IIa), (IIb), (IIc) or (IId); R4,R5,R6 = 1-12C alkyl or phenyl; R7,R8 = H, 1-12C alkyl or phenyl; or R7+R8 = (CH2)4-, -(CH2)5- or 3-oxa-1,5-pentylene; R9 = H or 1-4C alky; R12 = 1-12C alkyl, 3-7C cycloalkyl, benzyl or phenyl or together = 5-12C alkylene; R13 = 1-12C alkylene or phenylene; M = H or an alkali metal; X- = the anion of a monobasic acid; Z = Cl, NR2, NH-(1-12C alkyl) or -A-CO-NH-R14-Si(Ra)n(OR15(3-n; A = NH or N-(1-12C alkyl); R14 = 1-12C alkylene; R15 = 1-12C alkyl; Ra = 1-4C alkyl or OR15; n = 0, 1 or 2. Also claimed are Ir and Rh complexes (II) with (I) and a monoolefin or diene ligand and their salts; inorganic or polymeric organic carrier materials to which (I) or (II) is fixed, methods of producing these materials, and a process for asymmetrical hydrogenation of cpds. with C or C-hetero-atom double bonds.
