Synthesis of the first polymer-supported tripodal triphosphine ligand and its application in the heterogeneous hydrogenolysis of benzo[b]thiophene by rhodium catalysis
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.
