Cationic Transannular Oligomerization of 1, 5, 9-Cyclododecatriene

本文研究1,5,9-环十二碳三烯在阳离子型引发剂AlCl_3和BF_3·OEt_2催化下进行的跨环聚合反应,考察各种反应条件对跨环聚合反应的影响。产物为白色粉末,分子量均在1096—1431之间。对其溶解性、核磁共振和红外光谱的分析,确认了它的结构。

In this paper, the cationic transannular oligomerization of 1, 5, 9-cyclododecatriene initiated by AlCl_3 and BF_3·OEt_3 has been studied. The influence of the reaction conditions on the transannular oligomerization has been investigated. The oligomer obtained appears to be a white powder, of which the number-average molecular weight is about 1096—1431. According to the spectra of NMR and IR, and the solubility of the resulting oligomer in polar solvents, the structure of the product is determined to be 3 (See Chinese text).
