YieldReaction ConditionsOperation in experiment
54% In propan-1-ol; for 0.5h;Heating; General procedure: The dimethyl derivatives (4,4?, 5,5? or 6,6?) of 3,3?-dinitro-2,2?-azobipyridine were synthesized from the respective hydrazo-derivatives obtained previously from 3-nitro-4(or 5 or 6)-methyl-2-hydrazine-pyridine, respectively. Syntheses of these hydrazo derivatives were very similar to the synthesis of 3,3?-dinitro-2,2?-hydrazobipyridine. Instead of ethanol n-propanol was used and its mixtures were heated at boiling temperature for 30 min in the water bath. 2.52 g (0.015 mol) of 3-nitro-4(or 5 or 6)-methyl-2-hydrazine-pyridine were used to synthesis. The synthesized red-brown needle-like crystals of 4,4?-dimethyl-3,3?-dinitro-2,2?-hydrazobipyridine melt with decomposition at 255C. The yield was 53.1%. The synthesized brown needle-like crystals of 5,5?-dimethyl-3,3?-dinitro-2,2?-hydrazobipyridine melt with decomposition at 285C. The yield was 54.0%. The synthesized dark-brown needle-like crystals of 6,6?-dimethyl-3,3?-dinitro-2,2?-hydrazobipyridine melt with decomposition at 275C. The yield was 51.0%. 1 g of the obtained in this way 4,4?(or 5,5? or 6,6?)-3,3?-dinitro-2,2?-hydrazobipyridine was used to obtain respective azo derivatives in the same way as 3NAP. The synthesized orange needle-like crystals of 4,4?-dimethyl-3,3?-dinitro-2,2?-azobipyridine (4M3NAP) melt with decomposition at 260C. The yield was 74.2%. The synthesized orange needle-like crystals of 5,5?-dimethyl-3,3?-dinitro-2,2?-azobipyridine (5M3NAP) melt with decomposition at 256C. The yield was 77.1%. The synthesized orange powder of 6,6?-dimethyl-3,3?-dinitro-2,2?-azobipyridine (6M3NAP) melt with decomposition at 206C. The yield was 80.3% [51,52,54].
