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).
