Syntheses of tetraazatriphenylenes (II, VI, VIII) from dihydroxynaphthalenes (I, V, VII) with formamide or trisformylaminomethane (Chart 1) are described. Reaction of ethyl 1, 3-hydroxy-2-naphthoate (III) with trisformylaminomethane afforded II and N2-(1, 3-dihydroxy-2-naphthoyl) formamidine (IV). Ammonolysis of III with formamidine acetate gave IV.
