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 PdH bond and NMR/FTIR studies for pre-catalyst activation mechanism were performed.

使用阳离子乙酰丙酮钯一个简单的协议络合物与单- /二齿膦配体与活化的BF ₃ ·OET ₂作为原位用于聚合-formed催化剂内/外-5- methoxycarbonylnorbornene（活动起来的混合物至1.1·10 ⁴ 克摩尔^{-已经开发了1}  h ^-1）或5-苯基降冰片烯（7.2·10 ⁵  g mol ^-1  h ^-1）和降冰片烯（3.3·10 ⁸  g mol ^-1  h ^-1）。观察到，配体的性质强烈影响催化活性。催化剂体系Pd（II）/ BF ₃·OEt ₂对降冰片烯与5-甲氧羰基降冰片烯的共聚也具有活性。将5-甲氧基羰基降冰片烯单插入Pd H键后进行异构体的DFT计算，并进行NMR / FTIR研究前催化剂的活化机理。
