An efficient, metal-free decarbethoxylative arylation protocol for the synthesis of α-aryl-α-fluoroamides from fluoromalonamates, under ambient reaction conditions using aryne as an electrophilic arylating agent, is reported. This decarbethoxylative arylation proceeds under mild conditions and provides a practical and effective entry to a wide range of α-aryl-α-fluoroacetamides. Interestingly, the
Silver‐promoted C−F bond formation in α‐bromoamides by using AgF under mild conditions is reported. This simple method enables access to tertiary, secondary, and primary alkyl fluorides involving biomolecular scaffolds. This transformation is applicable to primary and secondary amides and shows broad functional‐group tolerance. Kinetics experiments revealed that the reaction rate increased in the order
The use of unsymmetricdiaryliodoniumsalts 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

An interesting substrate-controlled reactivity switch has been observed in the reaction of α-fluoro-β-ketoamides with arynes. The reaction of secondary α-fluoro-β-ketoamides with arynes provided access to α-aryl-α-fluoroacetamides through an arylation/deacylation sequence. Interestingly, the reaction of tertiary α-fluoro-β-ketoamides resulted in the C–C σ-bond insertion reaction to afford 1,2-disubstituted
