摘要: Photoredox-catalyzed direct keto-difluoroacetylation of styrenes with (fluorosulfonyl)difluoroacetate and dimethyl sulfoxide as an oxidant is disclosed. A variety α-difluoroacetylated ketones bearing functional groups good yields are obtained using fac-Ir(ppy)3 a photocatalyst under visible light irradiation.
