Аннотация
A simple protocol using cationic acetylacetonate palladium complexes with mono-/bidentate phosphine ligands activated with BF3·OEt2 as in situ-formed catalyst for polymerization of endo/exo mixture of 5-methoxycarbonylnorbornene (activity up to 1.1·104 g mol− 1 h− 1) or 5-phenylnorbornene (7.2·105 g mol− 1 h− 1), and norbornene (3.3·108 g mol− 1 h− 1) have been developed. It was observed that the ligands nature strongly influence the catalytic activity. The catalyst system Pd(II)/BF3·OEt2 was also active for the copolymerization of norbornene with 5-methoxycarbonylnorbornene. DFT calculations of isomers upon single insertion of 5-methoxycarbonylnorbornene into Pd–H bond and NMR/FTIR studies for pre-catalyst activation mechanism were performed.
