Metal-free electrochemical C3-sulfonylation of imidazo[1,2-<i>a</i>]pyridines

Abstract

An electrochemical C3-sulfonylation of imidazo[1, 2-<italic>a</italic>]pyridines with sodium benzenesulfinate has been developed, providing an straightforward protocol towards biologically and synthetically useful 3-(arylsulfonyl)imidazo[1, 2-<italic>a</italic>]pyridine.
