Article

The oxidative nucleophilic alkoxylation of 1,3,7-triazapyrene under acid catalysis conditions is preceded by diprotonation of the substrate. 6,8-Dialkoxy-1-methyl-1,3,7-triazapyrenium salts were synthesized. An unusual transformation of 6,8-diethoxy- and 6,8-dipropoxy-1,3,7-triazapyrenes to 1,3-dimethyl-6,8-dioxo-1,6,7,8-tetrahydro-1,3,7-triazapyrenium salts was found.
