The reaction of arylsulfonyl hydrazides with tertiary amines provided β‐amidovinyl sulfones in good yields under mild electrochemical conditions. The reactions were carried out using an acid, in a solution of n Bu 4 NBF 4 in dimethyl sulfoxide in undivided cells with graphite‐platinum electrodes under a constant current. The arylsulfonyl hydrazides and tertiary amines were activated via a radical process by electrochemical oxidation and reacted to give the desired β‐amidovinyl sulfones.
