Abstract
The invention relates to chiral ferrocenyls of formula (I) ##STR1## wherein R.sub.a is --P(R.sub.10 R.sub.11) or --SR.sub.12 ; R.sub.b is --P(R'.sub.10 R'.sub.11), --SR'.sub.12, --CH.dbd.NR.sub.12, --CH.sub.2 --NH--R.sub.12 or --CH.sub.2 --O--P(R.sub.10 R.sub.11); and the other substituents are as defined in claim 1, which may be used as ligands for transition metal catalysts in enantioselective reactions.
