本论文分两个部分,第一部分“全氟及多氟烷基卤化物的亚磺化脱卤反应”对连二亚硫酸钠与全氟烷基碘化物的作用进行考察,在碘化物S-碘-3-氧杂-八氟磺酸钠进行亚磺化脱碘反应并得到验证后,将反应用于其他带极性基因的全氟烷基碘化物上,随即采用相转移催化及共溶剂技术将反应推广到一般的全氟碘代烷上,证明连二亚硫酸钠对广谱的全氟烷基碘化 This thesis is divided into two parts, the first part of the “sulfonated dehalogenation of perfluoro and polyfluoroalkyl halides” on the sodium dithionite and perfluoroalkyl iodide role were investigated in iodine S-iodine - After 3-oxa-sodium octafluorosulfonate was subjected to sulfitation deiodination reaction and verified, the reaction was applied to perfluoroalkyl iodide with other polar genes, followed by phase transfer catalysis and co-solvent technique The reaction was generalized to perfluoroalkyl iodides, demonstrating that sodium dithionite is a good candidate for a broad spectrum of perfluoroalkyl iodides
