Oxidation ofN,N′-Diarenesulfonylhydrazines

Abstract N,N′-Diarenesulfonylhydrazine was oxidized with several oxidizing regents, but diarenesulfonyl diimide was not isolated. Diarenesulfonyl diimide produced immediately decomposed with evolution of 1 mol of nitrogen, and afforded the corresponding sulfonyl bromide, α-disulfone and sulfonic acid. Plausible mechanisms of decomposition were discussed.
