A metal- and oxidant-free intramolecular dehydrogenative N-N bond formation has been developed under mild and scalable electrolytic conditions. Various valuable 1,2,4-triazolo[1,5-a]pyridines were synthesized efficiently from the readily available N-(2-pyridyl)amidines. The reactions were conducted in a simple undivided cell under constant current conditions with nBu4NBr as both the redox mediator and the electrolyte. This protocol was applied to the efficient synthesis of key intermediates for anti-diabetic compounds.

The biologically important 1,2,4-triazolo[1,5-a]pyridines were readily synthesized from N-(pyridin-2-yl)benzimidamides via phenyliodine bis(trifluoroacetate)-mediated intramolecular annulation. This novel strategy allows for the convenient construction of a 1,2,4-triazolo[1,5-a]pyridine skeleton through direct metal-free oxidative N-N bond formation, featuring a short reaction time and high reaction yields.
