A chiral bipyridine zinc(II) complex, Zn(L)Cl2 (L=chiral bipyridine), has been prepared and characterized by usual spectroscopic means and X-ray crystallography. Reaction of Zn(L)Cl2 with AgCF3SO3 gave Zn(L)(CF3SO3)2insitu; this complex is an active catalyst for allylation of aldehydes with enantiomeric excesses up to 60%.
