The 1,3- and 1,4-bis(3-nitrofurazan-4-yl)benzenes have been synthesized by dehydration of 1,3- and 1,4-bis(2-aminoglyoximo-1-yl)benzenes followed by oxidation of amino groups. The 1,3- and 1,4-bis(3-nitrofuroxan-4-yl)benzenes have been prepared by nitrozylation of tetrapotassium salts of 1,3- and 1,4-bis(2,2-dinitro-1-oximinoethyl)benzenes and thermally isomerized to 1,3- and 1,4-bis(4-nitrofuroxan-3-yl)benzenes.
