Abstract

A series of catalytic systems based on palladium complexes with phosphine-thioether ligands has been investigated in the additive polymerization of norbornene and its derivatives. The effects of the solvent nature and monomer concentration on the yield of the additive polynorbornenes synthesized in the presence of pre-catalysts of the (P,S)Pd(CH₃)Cl structure, activated using AgSbF₆, have been established. Cationic palladium complexes of the [(P,S)Pd(CH₃)(L)]⁺(X)⁻ composition (where L = CH₃CN, DMSO, or 3,5-lutidine; X = BF₄, SbF₆) have been synthesized for the first time and characterized by means of ¹H, ¹³C, and ³¹P NMR spectroscopy. Additive polymerization of norbornene in the presence of these cationic complexes has been investigated. The effect of the labile ligand and the counterion on the activity of the cationic palladium phosphine-thioether complexes in the additive polymerization of norbornene has been established. The activity of palladium cationic complexes in additive polymerization is significantly affected by the addition of B(C₆F₅)₃, which binds the ligand L and promotes the dissociation of the complex into its active form.

甲基钯与膦硫醚配合物催化体系下降冰片烯及其衍生物的加成聚合

研究了一系列以磷硫醚为配体的钯配合物催化降冰片烯及其衍生物的加成聚合反应。研究了在AgSbF6活化的（P，S）Pd(CH3)Cl结构预催化剂存在下，溶剂性质和单体浓度对添加剂聚降冰片烯产率的影响。首次合成了[(P，S)Pd(CH3)(L)]+(X)−（L = CH3CN， DMSO，或3,5-lutidine; X = BF4, SbF6）的阳离子钯配合物，并通过1H， 13C和31P NMR谱进行了表征。研究了在这些阳离子配合物的存在下降冰片烯的加性聚合。研究了降冰片烯加成聚合过程中，不稳定配体和反离子对阳离子磷硫醚钯配合物活性的影响。添加B(C6F5)3对钯阳离子配合物的活性有显著影响，B(C6F5)3与配体L结合，促进配合物解离成活性形式。
