Electrochemical Synthesis of [1,2,3]Triazolo[1,5‐a]pyridines through Dehydrogenative Cyclization

Abstract The synthesis of [1,2,3]triazolo[1,5‐ a ]pyridines through electrochemical dehydrogenative cyclization of hydrazones of 2‐acylpyridines is presented. The reactions are carried out under mild conditions without oxidizing reagents or transition‐metal catalysts.
