Acrylate polymerizations catalyzed by Lewis pairs (LP) composed of B(C₆F₅)₃ and various Lewis bases (phosphines, amines, and an N-heterocyclic carbene) in dichloromethane were investigated using two procedures based on different monomer/catalyst addition sequences. In procedure 1, Lewis bases were added to B(C₆F₅)₃-activated n-butyl acrylate (nBA), and the polymerization proceeded quantitatively using all Lewis bases at a wide temperature range (−60 °C to 30 °C). A low nucleophilic Lewis base Et₃N also initiated the polymerization even at −60 °C. However, t-butyl acrylate was not polymerized, as LP promoted its conversion into acrylic acid and isobutene. In procedure 2, nBA was added to interacting LPs; the type of Lewis base significantly affected the polymerization results. Specifically, polymerization was not observed when 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and PⁿBu₃ were applied; however, similar to the reaction in procedure 1, PPh₃, P^tBu₃, and 1,4-diazabicyclo[2.2.2]octane (DABCO) initiated nBA polymerization. The pairing interactions between LBs/B(C₆F₅)₃ (PPh₃, Et₃N, DBU, and DABCO) were investigated using the shift of ¹⁹F nuclear magnetic resonance signals, demonstrating that weak interacting LPs efficiently initiated the polymerizations in procedure 2.

使用基于不同单体/催化剂添加顺序的两种程序研究了二氯甲烷中由 B(C ₆ F ₅ ) ₃和各种路易斯碱（膦、胺和 N-杂环卡宾）组成的路易斯对 (LP) 催化的丙烯酸酯聚合。在程序1中，将路易斯碱添加到B(C ₆ F ₅ ) ₃ -活化的丙烯酸正丁酯( n BA)中，并使用所有路易斯碱在宽温度范围(-60℃至30℃)下定量进行聚合反应。 C）。即使在-60 °C 下，低亲核路易斯碱 Et ₃ N 也能引发聚合。然而，丙烯酸叔丁酯没有聚合，因为LP促进其转化为丙烯酸和异丁烯。在程序2中，n BA被添加到相互作用的LP中；路易斯碱的类型显着影响聚合结果。具体而言，当使用1,8-二氮杂双环[5.4.0]十一碳-7-烯(DBU)和P ⁿ Bu _{3时，没有观察到聚合；}然而，与程序 1 中的反应类似，PPh ₃、P ^t Bu ₃和 1,4-二氮杂双环[2.2.2]辛烷 (DABCO) 引发n BA 聚合。^利用19 F 核磁共振信号的位移研究了LBs/B(C ₆ F ₅ ) ₃ (PPh ₃、Et ₃ N、DBU 和 DABCO)之间的配对相互作用，证明弱相互作用的 LPs 有效引发了聚合程序 2.
