摘要

Abstract New methods were proposed for synthesizing 1, 4, 5, 8-tetrakis (dimethylamino) naphthalene with an overall yield of 4 to 12% to replace the known procedure ensuring an overall yield of 2%. Catalytic hydrogenation was shown to be inapplicable for preparation of polyaminonaphthalenes from nitro compounds having 3 or 4 nitro gruops in the α-positions. Nucleophilic amination of 1, 5-dinitronaphthalene in the system NH 2 OH/NaOH/MeOH ...
