Living polymerization of phenylacetylenes catalyzed by cationic rhodium complexes bearing tetrafluorobenzobarrelene
2011
Binary catalysts composed of cationic rhodium complexes, [(tfb)Rh(L)2]X (tfb: tetrafluorobenzobarrelene, L: phosphine ligand, X: counter anion), and iPrNH2 induced living polymerization of phenylacetylene and its ring-substituted derivatives. The living nature was confirmed by kinetic plots of the polymerization. Nuclear magnetic resonance studies revealed that iPrNH2 serves to dissociate the coordinating PPh3 ligand of [(tfb)Rh(L)2]X to form an initiating species. Block copolymers were synthesized by the sequential polymerization of different phenylacetylenes using the present catalyst.
