A photocatalyst-free visible-light-promoted remote C(sp3)–H heteroarylation of N-fluoroamides with quinoxalin-2(1H)-ones was developed. All types of δ-C(sp3)–H bonds in the N-fluoroamides could be site-specific activated through the 1,5-HAT proc

A photocatalyst-free visible-light-promoted tandem intramolecular cyclization/heteroarylation between bromodifluoroacetamides and quinoxalin-2(1H)-ones or coumarins was developed. The process could generate a broad range of α,α-difluoro-γ-lactams.
