[摘要]: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, piperidyl, and carboxylic acid), whereas anhydride, N-Boc, or TMS functionalities do not withstand reaction conditions. |
