Related Products of 28682-70-4, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 28682-70-4, Pyridazine-4,5-diamine, introducing its new discovery.
4-Nitro-3-R1-6-R2-pyridazines (1) (a, R1 = R2 =2-pyridyl; b, R1 = H, R2 = phenyl; c, R1 = H, R2 = p-methoxyphenyl; d, R1 = R2 = H) are aminated by liquid ammonia/potassium permanganate to the corresponding 5-amino-4-nitropyridazines 3a-d.The 4-cyano-3-R1-6-R2-pyridazines 4a,b are only aminated in the presence of potassium amide in liquid ammonia/potassium permanganate to give the 5-amino-4-cyanopyridazines 6a,b.The 5-amino-4-nitropyridazines 3a,b,d are converted to the 4,5-diaminopyridazines 7a,b,d by reduction over a Pd/C catalyst.Reaction of7b with glyoxal leads to 5-phenylpyrazino<2,3-d>pyridazine (8b).
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Related Products of 28682-70-4. In my other articles, you can also check out more blogs about 28682-70-4
