Abstract
This study reveals a transition metal and external oxidant free electrochemical method for the C3-H sulfonylation of bio-logically diverse 2H-indazoles at room temperature and under ambient air. Using various sulfonyl hydrazides as the sulfonyl precursor, a series of sulfonylated indazole derivatives containing a broad spectrum of functional groups were synthesized up to 92% yield. Mechanistic studies suggest a precedented radical pathway is operating in the electrochemical pro-cess.
