The use of unsymmetric diaryliodonium salts as a versatile class of arylating agents has been demonstrated by developing a novel strategy to quickly access α‐arylated α‐fluoroacetoacetamides. The protocol provides a convenient metal‐free method for the α‐arylation of a diverse class of fluorinated acetoacetamides, and the products are obtained in good yields. The strategy, upon use of electron‐deficient diaryliodonium salts as an arylating agent, provides α‐fluoroacetamides through a spontaneous arylation/deacylation cascade.

不对称二芳基碘鎓盐在α-氟乙酰乙酰胺的α-芳基化反应中的利用

通过开发一种快速获取α-芳基化α-氟代乙酰胺的新颖策略，已证明了使用不对称的二芳基碘鎓盐作为通用的芳基化剂。该协议为各种类型的氟化乙酰乙酰胺的α-芳基化提供了一种便捷的无金属方法，并且产品收率很高。该策略在使用缺电子的二芳基碘鎓盐作为芳基化剂时，通过自发的芳基化/去酰化级联反应提供α-氟乙酰胺。
