- Abstract
- A direct cross-coupling between sodium sulfinates and 2H-indazoles has been developed under electrochemical conditions. The utilization of a graphite anode and platinum cathode in an undivided cell with a constant current of 7 mA allowed the concurrent oxidations of sulfinates and 2H-indazoles to sulfonyl radical and radical cationic 2H-indazoles, facilitating the direct radical-radical coupling strategy to 3-sulfonylated 2H-indazole derivatives. The transition-metal- A nd redox-reagent-free synthetic approach should serve as a valuable synthetic tool to achieve heteroaromatic compounds. Copyright © 2020 American Chemical Society.
