Iron-catalyzed C–N bond formation via oxidative C sp3 –H bond functionalization adjacent to nitrogen in amides and anilines: Synthesis of N -alkyl and N -benzyl azoles

Iron catalyzed oxidative protocol was developed to couple azoles with amides to generate N-alkylazole derivatives in moderate to excellent yields using tertiarybutyl hydroperoxide as an oxidant under mild reaction conditions. Furthermore, this protocol explored to couple azoles with N-alkylanilines, unexpectedly N-benzyl azoles were obtained as major products under these oxidative conditions.
