碘代全氟烷与连二亚硫酸钠进行的亚磺化脱碘反应具有自由基反应的特征,从而提供了用化学方法截捕全氟烷自由基中间体的可能性.我们用烯烃作为自由基截捕剂,得到了碘代全氟烷与烯烃的自由基链式反应产物.由不同烯烃可得到1∶1的加成物或调聚物.本文对加成反应与亚磺化脱碘反应的关系及阻聚剂对反应的影响进行了探讨.
The iodination of perfluoroalkanes and sodium dithionite for their sulfidated deiodination reactions are characteristic of free radical reactions and thus provide the possibility of chemically trapping perfluoroalkane radical intermediates. We use olefins as a radical scavenger The results showed that the product of free radical chain reaction between iodo perfluoroalkane and alkene was obtained.The adduct or telomer of 1: 1 could be obtained from different olefins.In this paper, the reaction of addition reaction with sulfonated deiodination Relationship and polymerization inhibitor on the reaction were discussed.
