cooperation of photoredox and hydrogen atom transfer (HAT) processes, defluoroalkylations of gem-difluoroalkenes occurred smoothly with alcohols under visible-light irradiation. Notably, the protocols feature broad scopes, mild conditions, and validity for the late-stage functionalization of bioactive molecule derivatives. Mechanistic studies suggested that the reaction occurred through the radical coupling
报道了一种可行且有效的合成α-氟烯基醇的方法。在光氧化还原和氢原子转移(HAT)过程的配合下,偕二氟烯烃在可见光照射下与醇顺利发生脱氟烷基化。值得注意的是,该协议具有范围广、条件温和、生物活性分子衍生物后期功能化的有效性等特点。机理研究表明该反应是通过烷基自由基和氟烯基自由基的自由基偶联发生的。
