  A new type of ferrocenyl diphosphine-imine ligands that contains an ionic salt group has been prepared, and successfully applied to asymmetric C*-O bond formation. In the Pd-catalyzed asymmetric allylic etherification of 1,3-diphenyl-2-propenyl acetate, high enantioselectivity was obtained (up to 91.0% ee). The potential of the catalysts to be recycled and reused has also been demonstrated. (C) 2011 Elsevier Ltd. All rights reserved.

  A variety of chiral tert-butanesulfinylphosphine ligands were prepared and applied to the palladium-catalyzed asymmetric allylic etherification of 1,3-diphenylpropenyl acetate with alcohols. Excellent yields and moderate enantioselectivities were obtained. The absolute configuration of the etherification products was evidently switched only through the position change of the substituent on the P-aryl groups. (C) 2012 Elsevier Ltd. All rights reserved.
