Regiospecific Synthesis of N 2-Aryl 1,2,3-Triazoles from 2,5-Disubstituted Tetrazoles via Photochemically Generated Nitrile Imine Intermediates

The synthesis of N2-aryl 1,2,3-triazoles from 2,5-disubstituted tetrazoles was achieved under photochemical conditions. This simple and mild one-step reaction provides regiospecific access to 2,4,5-substituted 1,2,3-triazoles via a nitrile imine intermediate. Syntheses of alkyl and heterocylic derivatives were also investigated.

Hypervalent iodine in synthesis 87: The synthesis of 2,5-diaryl-2H- tetrazoles

In the presence of cuprous iodide and potassium carbonate, N-arylation of 5-aryl-2H-tetrazole with a diaryliodonium salt proceeds smoothly in DMF at room temperature to give 2, 5-diaryl-2H-tetrazoles in moderate to good yield.
