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 method for the preparation of imidazolines and benzimidazoles bearing an amide at the 2-position, is described. The reactions of the glyoxamide with aliphatic and aromatic 1,2-diamines were found to form five-membered imidazolines and benzimidazoles by a one-pot condensation-oxidation procedure.
