hydrodifluoromethylation of alkenes is reported using difluoroacetic acid and phenyliodine(III) diacetate in tetrahydrofuran under visible‐light activation. This metal‐free approach stands out as it uses inexpensive reagents, does not require a photocatalyst, and displays broad functional group tolerance. The procedure is also operationally simple and scalable, and provides access in one step to high‐value
据报道,在可见光下,在四氢呋喃中使用二氟乙酸和二乙酸苯碘(III),是一种用于烯烃的区域选择性氢二氟甲基化的简便方法。这种无金属方法因其使用廉价的试剂,不需要光催化剂且具有宽泛的官能团耐受性而脱颖而出。该程序在操作上也很简单且可扩展,并且一步一步即可提供用于药物化学的高价值构建基块。
