This paper describes the synthesis of 3,3′bis(2,2′,4,4′,6,6′‐hexanitrostilbene) (5) . Based on the Ullmann reaction we prepared the title compound in nitrobenzene by using 3‐chloro 2,2′,4,4′,6,6′‐hexanitroztilbene (4) as the starting material and copper powder as the catalyst. (4) was reacted with hydrazine, not to yield a desired product, azo‐3,3′bist(2,2′,4,4′,6,6′‐hexanitrostilbene.) but to form a well‐known explosive, 2,2′,4,4′,6,6′‐hexanitrostibene (6). Differential scanning calorimetrical analysis has shown that (5) begins to decompose at the temperature of 298°C.
