Process for the asymmetric hydrogenation of ketocarbonic acid esters

摘要

Substances comprising a metal complex with an enantiomer-enriched chiral bidentate diamine ligand adsorbed on a micro-, meso- or macroporous support are new. Substances comprising a metal complex of formula (I) adsorbed on a micro-, meso- or macroporous support are new: (L)nMQ (sulfonate-)p (I) Q : an enantiomer-enriched chiral bidentate diamine ligand; M : an m-valent metal cation; L : an anionic or neutral ligand; p : 1 or 2; n : 1-4. Independent claims are also included for: (1) catalysts comprising the substances; (2) catalytic production of enantiomer-enriched compounds using the catalysts.
