  peri-Naphthylenediamines. 38. Naphthalene and acenaphthene “proton sponges” with +M substituents in ortho positions with respect to peri-dimethylamino groups

  摘要：

  Previously unknown 4,5,6,7-tetrakis(dimethylamino)acenaphthene, which is the first acenaphthene derivative containing four vicinal dialkylamino groups, was synthesized based on 5,6-bis(dimethylamino)-4,7-dinitroacenaphthene. The total synthesis of 1,2,7,8-tetrakis(dimethylamino) naphthalene was carried out starting from 3,6-dinitronaphthalic anhydride. Other "proton sponges" of this type, viz., 1,7,8-tris((dimethylamino)-2-methoxy- and 1, 8 -bis(dimethylamino)-2,7-dipiperidinonaphthalenes, were prepared by the nucleophilic substitution in 2,7-dimethoxy-1,8-dinitronaphthalene. In solutions, 1,2,7,8-tetrakis(dimethylamino)naphthalene and its analogs can form di- and trications in the presence of acids. The basicity constants pK(a)(1) of the compounds measured in DMSO depend in a complex way on their structures but correlate with the basicity index B, which is determined by changes in the Chemical Shifts 811 after the addition of the first proton. Due to low C-nucleophilicity of ortho-disubstituted "proton sponges" in combination with high basicity, these compounds hold considerable promise as reagents in organic synthesis.

  ohols) with good to excellent yields. Steric hindrance does not prevent the reaction. Some amines with electron-withdrawing groups, especially at nonconjugated positions, are also alkylated. The procedure allows the combination of a reduction (catalytic or by tin dichloride in acidic media) and a methylation in a one-pot process. (© Wiley-VCH Verlag GmbH & Co.
