Title:
1,2-DISUBSTITUTED RUTHENOCENE PLANE CHIRALITY LIGAND
Document Type and Number:
WIPO Patent Application WO/2009/043300
Kind Code:
A1
Abstract:
A 1,2-disubstituted ruthenocene chiral ligand of formula(1)or(2)comprises
central chirality and plane chirality which have S structure or R structure and
its preparation. Substituent R of formula(1)or(2)represents linear alkyl
or branch-alkyl .The ligand can be used in all kinds of metallic catalysis asymmetric
reaction.
