| Abstract: | PdCl 2 CuCl 2 Chiral phosphines catalyst systems have good enantioselectivities and regioselectivities to hydroesterification of styrene. Three kinds of ligands were used. High optical purity and good chemical yields have been obtained by using the ligand DDPPI for PdCl 2 CuCl 2 catalyzed reaction. The effects of P/Pd ratio, reaction pressure, and solvent have been also investigated with this catalyst system. Asymmetric induction up to 99.0% e.e. and good regioselectivities have been obtained in the hydroesterification of styrene with carbon monoxide and alcohol. |
