A convenient synthesis of new chiral ferrocenene-bridged phosphole-phosphane ligands in an enantiomerically pure form has been developed. These new chiral PP ligands have been tested in a palladium-catalysed allylic substitution reaction. High activities and moderate enantioselectivities (up to 61 %) were observed. A palladium(II) complex has been isolated and its crystal structure established.
