Abstract
A p-styrenyl substituent attached to the ligand framework allows the tripod al triphosphine moiety -C(CH2PPh2)(3) to be introduced as a pendant group i n polystyrene matrices via free-radical copolymerisation; in conjunction wi th rhodium(i), the polytriphos material forms an effective heterogeneous ca talyst for the hydrogenolysis of benzo[b]thiophene to 2-ethylthiophenol and ethylbenzene.
