Abstract
Substituted tetraazapentalenes have two benzenoid rings and eight substitutable positions. Substitutions are made of hydrogen or C—H groups in favor of amino groups, nitro groups or nitrogen atoms. The tetraazapentalenes are synthesized through an intermediate azo, which is made from a 1:1:1 molar ratio of a nitroaniline, sodium nitrite and an amine.
