Reactions of 3-aroylacrylates with 伪-aminoazoles was written by Kolos, N. N.;Kovalenko, L. U.;Borovskoy, V. A.. And the article was included in Chemistry of Heterocyclic Compounds (New York, NY, United States) in 2011.Recommanded Product: 6-(4-Chlorophenyl)pyridazin-3(2H)-one This article mentions the following:
Dihydro derivatives of pyrazolo[3,4-b]pyridine-, pyrazolo[1,5-a]pyrimidine-, and [1,2,4]triazolo-[1,5-a]pyrimidinecarboxylates have been prepared by cyclocondensation of 尾-aroylacrylates with 5-aminopyrazoles and 3-amino-1,2,4-triazole. Heating dihydro[1,2,4]triazolo[1,5-a]pyrimidine-7-carboxylates with hydrazine hydrate led to recyclization of the pyrimidine ring to form 6-arylpyridazin-3(2H)-ones. In the experiment, the researchers used many compounds, for example, 6-(4-Chlorophenyl)pyridazin-3(2H)-one (cas: 2166-13-4Recommanded Product: 6-(4-Chlorophenyl)pyridazin-3(2H)-one).
6-(4-Chlorophenyl)pyridazin-3(2H)-one (cas: 2166-13-4) belongs to pyridazine derivatives. Pyridazine and phthalazine have quite different spectroscopic properties compared with their isomers, pyrazine and quinoxaline. Pyridazine and derivatives coordinate readily with transition metals to form complexes and catalysts with synthetic utility.Recommanded Product: 6-(4-Chlorophenyl)pyridazin-3(2H)-one
