US 6,143,834 A · Optically active phosphine derivative having at least two vinyl groups, polymer produced using the same as monomer, and transition metal complexes of these

Abstract

A transition metal complex of a polymer of 2'-diarylphosphino-1,1'-biphenylen-2-yloxy(6,6'-divinyl-1,1'-binaphthalene -2,2'-diyloxy)phosphine derivative is disclosed, which is represented by general formula (I): ##STR1## wherein Ar is an optionally substituted phenyl or naphthyl; R.sup.1 and R.sup.2 each independently is a hydrogen atom, a lower alkyl, a lower alkoxy, etc.; and R.sup.3 is a lower alkyl, a lower alkoxy, etc.; provided that R.sup.2 and R.sup.3 may be bonded to each other to form a hydrocarbon ring, which may have one or more substituents selected from lower alkyl groups, halogen atoms, vinyl, etc. Also disclosed are a polymer having structural units derived from the phosphine derivative and a transition metal complex obtained by causing a transition metal compound to act on the phosphine derivative or the polymer. A novel polymer-supported ligand is provided which, when used as a catalyst for asymmetric syntheses, gives satisfactory results concerning catalytic activity, enantiomer excess, etc.
