. We present a new metal‐free photocatalytic approach for the synthesis of difluoroalkoxylated ketones. This strategy involves the generation of alkoxyl radicals from pyridinium salts upon the activity of a catalytic electron‐donor‐acceptor (EDA) complex. This mild process tolerates several functional groups and can be scaled up to gram scale. Diverse products manipulations accounts for the versatility of the obtained fluorinated products, highlighting the synthetic usefulness of this method.

二氟烯醇甲硅烷基醚自由基分子间烷氧基化光催化合成α-二氟烷氧基酮


。我们提出了一种新的无金属光催化方法来合成二氟烷氧基化酮。该策略涉及在催化电子供体受体（EDA）复合物的活性下从吡啶鎓盐生成烷氧基自由基。这种温和的过程可耐受多种官能团，并且可以放大至克级。多样化的产品操作说明了所获得的氟化产品的多功能性，突出了该方法的合成实用性。
