The mechanism was supposed as follows: polyfluoroalkyl iodides were initiated by sodium dithionite to give R〓 which was added to one double bond of diallylacetic acid, after the sequential radical cyclization and nucleophilic substitution to form bicyclo-lactones.

这是因为：多氟烷基碘化物在连二亚硫酸钠的引发下，得到自由基R〓，后者加成到二烯丙基乙酸中的一个—C=C—双键上，然后在碱性介质中进行分子内亲核反应得到双环内酯类产物。

Polyfluoroalkyl iodides could react with unsaturated olefin acids in the presence of sodium dithionite by radical addition to give adducts. It was found that these adducts could form polyfluoroalkyl substituted γ or δ-lactones due to intramolecular nucleophilic substitution in the alkali solution.

研究发现：多氟烷基碘化物在连二亚硫酸钠存在下与不饱和烯酸经自由基加成得到的产物，能在碱性条件下进行分子内亲核取代反应形成五元或六元环的含氟内酯类化合物。
