Cycloaddition reaction of 2,5‐bis(trifluoromethyl)‐1,3,4‐oxadiazole with strained olefinic bonds of norbornenes was used to synthetize functionalized polynorbornanes. This simple, one step procedure was more effective when reaction was carried out by classical heating, in comparison to microwave‐assisted reactions. Various functional groups were stable in the reaction conditions (ester, imide, phthalimide
2,5-双(三氟甲基)-1,3,4-恶二唑与降冰片烯的张紧烯键的环加成反应用于合成官能化的聚降冰片烷。与微波辅助反应相比,当通过经典加热进行反应时,这一简单的一步操作程序会更加有效。各种官能团在反应条件下稳定(酯,酰亚胺,邻苯二甲酰亚胺,哌啶基和羧酸),而酸酐,N- Boc或TMS官能团不能承受反应条件。
