cleavage of three C–X bonds, including two inert C(sp3)–F bonds on bromodifluoroacetamides, while leaving C–C bonds intact. This strategy will undoubtedly further consummate the role of halo difluoro compounds and enrich both fluorine chemistry and pharmaceutical sciences.

A novel and simple method for the direct amidation of azoles with formamides has been developed. The reaction could occur smoothly in the presence of tert-butyl perbenzoate (TBPB) as an oxidant under metal- and base-free conditions. Direct dehydrogenativecross-coupling of formamides and azoles generated the corresponding products in good yields.
