The major product was switched depending on the cation radical being used. That is, s-triazolo[4,3-α]pyridines (2), an intramolecular cyclization product, and 1-(2-pyridyl)-1,2,4-triazoles (3), an intermolecular cycloaddition product, were obtained as a major product when reacted with and , respectively in nitrile solvents. The plausible mechanisms are proposed based on both the reduction potentials of and and control experiments.Read More
