ABSTRACT:
A phosphine-phosphinite compound represented by formula (I): ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, each represent a substituted or unsubstituted phenyl group or a substituted or unsubstituted naphthyl group, and a process for preparing a The compound (I), either in combination, or as a complex, with a transition metal compound, is useful as a catalyst for asymmetric hydroformylation and makes it possible to easily synthesize an important intermediate for carbapenem antibiotics or a precursor thereof at high regioselectivity and diastereo-selectivity.
