- peri-naphthylenediamines 29. 1,8-Bis(dimethylamino)-3-nitro- and -3,6-dinitronaphthalenes and 5,6-bis(dimethylamino)-3-nitro- and -3,8-dinitroacenaphthenes as the first representatives of "proton sponges" meta-substituted relative to NMe2 groups
-
meta-Substituted "proton sponges" were prepared for the first time by the direct nitration of 5,6-bis(dimethylamino)acenaphthene under strong acidic conditions and by the selective reduction of 1,3,8-tri- and 1,3,6,8-tetranitronaphthalenes and subsequent alkylation of the compounds obtained. 4,5-Bis(dimethylamino)-1,2,3,6,7,8-hexanitronaphthalene was synthesized starting from 1,3,6,8-tetranitronaphthalene.
