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
Va. Ozeryanskii et Af. Pozharskii, 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, RUSS CHEM B, 49(8), 2000, pp. 1399-1405
meta-Substituted "proton sponges" were prepared for the first time by the d
irect nitration of 5,6-bis(dimethylamino)acenaphthene under strong acidic c
onditions and by the selective reduction of 1,3,8-tri- and 1,3,6,8-tetranit
ronaphthalenes and subsequent alkylation of the compounds obtained. 4,5-Bis
(dimethylamino)-1,2,3,6,7,8-hexanitronaphthalene was synthesized starting f
rom 1,3,6,8-tetranitronaphthalene.
