| Abstract: | A simple and convenient method for the synthesis of 1,4‐diazabutadienes (=N,N′‐ethane‐1,2‐diylidenebisamines]) by grinding glyoxal (=ethanedial) or an α‐diketone and anilines (=benzenamines) in the presence of TsOH in a mortar with a pestle is described. By this way, 1,4‐diazabutadienes were obtained in good to excellent yields. |
