Asymmetric allylic alkylation in supercritical carbon dioxide using P-chiral diamidophosphite ligands

P*-Chiral diamidophosphite ligands in the Pd-catalyzed allylic alkylation of ( E)-1,3-diphenylallyl acetate in supercritical carbon dioxide provide enantioselectivities up to 90% ee. The catalytic performance is affected greatly by temperature, CO 2 pressures and structure of catalysts.
