A novel three‐component condensation reaction of benzotriazoles, aldehydes and tertiary anilines efficiently catalyzed by readily available organic acid p‐toluenesulfonic acid (PTSA) has been developed. A series of N‐alkyl benzotriazoles were synthesized in up to 97% yield for 21 examples starting from anilines, benzotriazoles and formaldehyde. This strategy features a simple system, atom economy,

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.
