Nitration of 1,8-bis(dimethylamino)naphthalene and 5,6-bis(dimethylamino)acenaphthene in neutral and weakly acidic media. The first case of isolation of o -nitro and o,o ′-dinitro derivatives of "proton sponges” [V. Ozeryanskii, A. Pozharskii, N. Vistorobskii] o-Nitro ando,o′-dinitro derivatives of 1,8-bis(dimethylamino)naphthalene and its acenaphthene analog were prepared for the first time by direct nitration with nitrogen dioxide or tetranitromethane. When 5,6-bis(dimethylamino)acenaphthene was treated with nitric acid in AcOH or MeCN or with nitronium tetrafluoroborate in MeCN, nitration was accompanied by partial demethylation of one of the NMe2 groups.
