A p-styrenyl substituent attached to the ligand framework allows the tripodal triphosphine moiety –C(CH2PPh2)3 to be introduced as a pendant group in polystyrene matrices via free-radical copolymerisation; in conjunction with rhodium(I), the polytriphos material forms an effective heterogeneous catalyst for the hydrogenolysis of benzo[b]thiophene to 2-ethylthiophenol and ethylbenzene.

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