N,N-disubstituted hydrazones react with sulpfenyl chloride, sulphur chlorides, sulphur dichloride, and disulphur dichloride to give C-sulphenyl products.N,N-tetramethylenehydrazones with SCl2 or S2Cl2 give the novel pyrrolo-1,3,4-thiadiazole ring system.Studies of the site selectivity in reactions of these hydrazones with sulphur(II) electrophiles by the semiempirical CNDO and MNDO methods are reported.
