Title:
CATALYST COMPRISING A CHIRAL CATIONIC METAL-LIGAND COMPLEX IMMOBILISED ON A MESOPOROUS ALUMINO-SILICATE SUPPORT, ITS PREPARATION AND USE IN ASYMMETRIC HYDROGENATION
Document Type and Number:
WIPO Patent Application WO2002036261
Kind Code:
B1
Abstract:
A solid catalyst for asymmetric hydrogenation reactions is disclosed comprising a chiral cationic metal-ligand complex immobilised on a mesoporous alumino-silicate support. The catalyst is formed by ion exchange with the acid sites of the support. The catalyst is reusable, and maintains its activity after use. The metal is preferably Rh, Ir or Ru. The ligands are preferably neutral ligands selected from the group consisting of BINAP, DuPHOS, BIPHEP, TMBTP, BITIANAP, BIBFUP, bppm, CARBOPHOS, JOSIPHOS, BPE, DEGPHOS, DIOP, BIPNOR, DIPAMP, CHIRAPHOS, PROPHOS, PYPHOS, BINAPAN, SELKE or formula (I), formula (II), formula (III).
