An unusual peri-dimerised product was obtained when subjecting 1,3,6,8-tetramethoxynaphthalene to Vilsmeier–Haack reaction conditions (POCl3/DMF). The formation of this peri-dimerised naphthaleneproduct suggests that 1,3,6,8-tetramethoxynaphthalene has comparable reactivity to that of Proton Sponge [1,8-bis(dimethylamino)naphthalene]. The octamethoxy peri-dimer was characterised using NMR spectroscopy
