In aqueous solution containing azide ion as a nucleophile, electrochemicaloxidation of hydroquinone and some dihydroxybenzoic acids have been studied using cyclic voltammetry and controlled-potential coulometry. The voltammetric data show that electrochemically generated para and ortho-benzoquinones participate in Michael addition reactions with azide ions to form the corresponding diazido or diaminobenzoquinones

efficient synthesis of diamino benzoquinone, beginning from catechol derivatives and hydroquinone with azide ion was developed in the presence of potassium ferricyanide as an oxidizing agent (Decker oxidation), the results of which revealed the participation of azide ion in Michael addition reactions with benzoquinones yield in situ. This study has made one-pot oxidative method possible for diamino benzoquinones

Described are methods and composition for inhibiting polymerization of a monomer (e.g., styrene) composition using an aminated quinone antipolymerant, such as an aminated benzoquinone or aminated naphthoquinone antipolymerant having one or more secondary or tertiary amine group(s). The aminated quinone antipolymerant can be used with little or no nitroxyl group containing antipolymerant yet still provide excellent antipolymerant activity in a monomer-containing composition.
