tert-Amines were harnessed to afford arenesulfonyl hydrazides and arenesulfonyl chlorides via a metal-, oxidant- and halogen-free electrochemical oxidative coupling in an undivided cell at RT. This environmentally benign approach afforded a wide spectrum of sulfonamides in satisfactory yields using cheap and renewable Pencil Graphite Electrodes (PGEs).
