Diazenyl 1,2,4‐triazol‐5(4 H )‐thione derivatives were synthesized in good yields via Eschenmoser‐coupling reaction and nucleophilic attack between 1,4‐disubstituted thiosemicarbazides and 2,3,5,6‐tetrachloro‐1,4‐benzoquinone ( p ‐CHL). The structure of the synthesized compounds was confirmed by IR, NMR and mass spectral data as well as single crystal X‐ray analysis.
