A simple and convenient method for the synthesis of 1,4‐diazabutadienes (= N , N′ ‐ethane‐1,2‐diylidenebis[amines]) 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.
