Abstract
The novel chiral diaqua palladium(II) complexes of (R)-BINAP 9a and (R)-Tol-BINAP 9b were prepared in good yield, and their structures were determined by X-ray crystallography. These air- and moisture-stable complexes were found to be excellent catalysts for the asymmetric aldol reaction, and up to 89% ee of asymmetric induction was achieved using these catalysts.Keywords
