Alternating copolymerization of ω-perfluoroalkyl-1-alkenes with carbon monoxide catalyzed by homogeneous and polymer-supported Pd-complexes
Alternating copolymerization of fluorinated olefins (C n F 2 n + 1 )(CH 2 ) m CH=CH 2 ( 1 ) and carbon monoxide was carried out using cationic Pd(II)-(R,S)-BINAPHOS complexes ( 2 ) as catalysts. To obtain polymeric products sufficiently, existence of at least two methylenes in 1 were essential (m 2)...
