Zhang, Hai-xiang; Hong, Dong-feng; Chen, Cheng-liang published the artcile< Synthesis of 4-aminopyridazine>, Category: pyridazine, the main research area is dichloro amino pyridazine amino synthesis yield.
The starting material 3,6-dichloropyridazine reacted with chlorine to produce 3,4,6-trichloropyridazine, then followed with methanol and ammonia to synthesize 3,6-dichloro-4-aminopyridazine, which via catalytic dechlorination reaction achieved object compound 4-amino pyridazine and gave a 48.2% overall molar yield. Its structure was analyzed and characterized through m.p. testing, 1H NMR and mass spectrometry.
Yingyong Huagong published new progress about 20744-39-2. 20744-39-2 belongs to class pyridazine, and the molecular formula is C4H5N3, Category: pyridazine.
