Photoredox-catalyzed direct keto-difluoroacetylation of styrenes with (fluorosulfonyl)difluoroacetate and dimethyl sulfoxide as an oxidant is disclosed. A variety of α-difluoroacetylated ketones bearing functional groups with good yields are obtained using fac-Ir(ppy)3 as a photocatalyst under visible light irradiation.
本文公开了一种光氧化还原催化的、以（氟磺酰基）二氟乙酸酯和二甲亚砜作为氧化剂的苯乙烯的直接酮二氟乙酰化反应。使用 fac-Ir(ppy)3 作为光催化剂，在可见光照射下，以良好的收率得到了多种带有官能团的α-二氟乙酰化酮。
