Molecular rearrangement of sulfur compounds(VII). A pyrolysis of arenesulfonylhydrazine derivatives

Article abstract of DOI:10.1080/10426509608046356

N-Phenyl-N′-arenesulfonylhydrazine(I-II) on pyrolysis by refluxing in an atmosphere of nitrogen at ca. 240°C give SO₂, H₂S, NH₃, arene, biaryl, aniline, azobenzene, diaryl sulfide, diaryl sulfone, arenesulfonic acid, phenyl hydrazine and carbazole derivatives. N-Benzylidene-N′-benzenesulfonylhydrazone(III) on similar treatment gives the previous products in addition to benzonitrile, bibenzyl, stilbene, 2-phenylindole and 2,3,4,5-tetraphenylthiophene. The observed results have been interpreted in terms of a free radical mechanism involving the homolysis of N - N and S - N bonds.
