We herein described a practical and efficient protocol for hydrodifluoromethylation of unactivated alkenes using readily available difluoroacetic anhydride as a difluoromethyl source by merging photocatalysis and N-hydroxyphthalimide activation. This method features a wide substrate scope and excellent compatibility with various functional groups, as demonstrated by more than 50 examples, including
我们在此描述了一种实用且有效的方案,通过结合光催化和N-羟基邻苯二甲酰亚胺活化,使用容易获得的二氟乙酸酐作为二氟甲基源,对未活化的烯烃进行氢二氟甲基化。该方法具有底物范围广、与各种官能团具有良好的相容性的特点,已有50多个例子证明,包括生物活性分子和药物衍生物。机理研究表明N-羟基邻苯二甲酰亚胺也可能作为氢原子供体。
