Chiral ferrocenyl phosphine-thioether ligands have been covalently bound on the periphery of 4 phosphorus dendrimers (generations 1-4) having a cyclotriphosphazene core and on one model compound. These new dendrimers proved to be efficient ligands for the palladium-catalyzed asymmetric allylic substitution reaction (ee up to 93%).
