摘要

The invention relates Ligand FERROCENILDIFOSFINA WITH A GROUP OF silylene, ferrocenyldiphosphines UNITED THROUGH THIS GROUP silylene to a support inorganic or organic polymer, their production and their metal with transition metals such as rhodium or iridium complexes. The invention relates also from the use of these complexes for hydrogenating LINKS ORGANICOS Two- and trivalent ESPECIALLY LINKS AND LINKS bivalent Olefin-carbon double hetero atom. The complexes are particularly suitable for hydrogenating ENANTIOSELECTIVE USING AND COMPOUNDS prochiral chiral diphosphines unsaturated. Obtaining these ferrocenyldiphosphines immobilized is possible by preparation of corresponding ferrocenyldiphosphines FUNCTIONAL. These compounds and their preparation are new. THEREFORE Another object of the invention are compounds of formula I wherein R SUB {1} is alkyl of C {SUB, SUB {1} -C, 8}, phenyl or 1 TO 3 alkyl C {SUB 1 -C {} SUB, 4} or phenyl substituted by alkoxy C {SUB, SUB 1} -C {4}; R SUB {2}, {R SUB, 3}, {R SUB, SUB {10} YR, 11} ARE independently of one another alkyl of C {SUB, SUB 1} -C {12}, cycloalkyl C {SUB, SUB {5} -C, 12}, phenyl, cycloalkyl C {SUB, SUB {5} -C 12 substituted with an alkyl} C {SUB, SUB {1} -C, 4} or an alkoxy of C {SUB, SUB {1} -C, 4} or one to three alkyls C {SUB, SUB 1} C {4}, {SUB alkoxy C 1 -C} {SUB, 4 }, {SIR SUB, SUB {4} R, 5} R {SUB, 6}, halogen, -SO SUB {3} M, -CO SUB {2} M {SUB PO 3 M}, - NR {SUB, 7} R {SUB, 8}, [{SUP, +} NR {SUB, 7} R {SUB, 8} R {SUB, 9}] X {SUP, -} or phenyl substituted one or more tIMES WITH SUB {fluoroalkyl C 1 -C} {SUB, 5}; Or groups -PR {SUB, SUB {2} R, -PR 3} {SUB, SUB 10} R {11} are, independently of one another, a radical of formula II, IIA, IIB or IIC, YR SUB {4}, {R SUB, SUB {5} YR, 6} are, independently of one another, alkyl of C {SUB, SUB 1} -C {12} or phenyl; {R SUB, SUB {7} YR, 8} are H, alkyl of C {SUB, 1} {SUB -C 12}, phenyl SUB OR {7} {SUB YR, 8} together form TETRAMETILENOS, PENTAMETILENOS O 3-OXA-1,5-pentylene, R SUB {9} {HO alkyl C SUB, SUB {1} -C, 4}; R SUB {12} are radicals identical or different and are independently of one another, alkyl of C {SUB, SUB 1} -C {12}, {SUB cycloalkyl C 3 -C} {SUB 7 }, benzyl or phenyl or TOGETHER alkylene of C {SUB, SUB {5} -C, 12}, {SUB YR, 13} is alkylene of C {SUB, SUB 1} -C {12} or phenylene, M It is HO alkali metal, X {SUP, -} is an anion of an acid monobasic, Z is Cl, NH {SUB, 2}, NH-alkyl C {SUB 1} -C {SUB, 12}, OR GROUP -A-CO-NH-R SUB {14} -Si (RA) SUB {N} (OR SUB {15}) {SUB, 3-N}, where A is NH ON (alkyl C { SUB, SUB 1} -C {12}), R {SUB, 14} is alkylene of C {SUB, SUB 1} -C {12}, {R SUB, 15} is alkyl of C {SUB 1 -C {} SUB, 12}, RA is alkyl of C {SUB, SUB {1} -C, 4} {O OR SUB, 15}, n is 0, 1 or 2; And compounds of formula I as racemates and diastereomers OR MIXTURES.
