An electrochemical difluoromethylation triggered lactonization of alkenes was developed for the first time. This protocol employs readily prepared CFHSONa as the difluoromethylating reagent, affording unprecedented CFH-containing lactones in moderate yields. Moreover, with CFSONa as the trifluoromethylating reagent, a wide array of CF-containing lactones were obtained under additional supporting electrolyte- and catalyst-free conditions.
首次开发了一种电化学二氟甲基化引发的烯烃内酯化反应。该方法使用易于制备的CFHSONa作为二氟甲基化试剂，以中等产率得到了前所未有的含CFH的内酯。此外，以CFSONa作为三氟甲基化试剂，在无需额外支持电解质和催化剂的条件下得到了多种含CF的内酯。
