Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Quality Control of 3-Amino-5-(4-phenoxyphenyl)pyrazole-4-carbonitrile, 330792-70-6, Name is 3-Amino-5-(4-phenoxyphenyl)pyrazole-4-carbonitrile, molecular formula is C16H12N4O, belongs to pyrazoles-derivatives compound. In a document, author is EL-mahdy, Kamelia M., introduce the new discover.
Easy preparation, characterization and reactions of new 8-chloro-7-formyl-4-oxo-2-phenyl-4H-pyrimido[1,2-a]pyrimidine-3-carbonitrile
8-Chloro-7-formyl-4-oxo-2-phenyl-4H-pyrimido[1,2-a]pyrimidine-3-carbonitrile (3) is constructed using N-(5-cyano-6-oxo-4-phenyl-1,6-dihydropyrimidin-2-yl) acetamide (2) via Vilsmeier-Haack formylation reaction. Compound 3 reacted with 3-(triethoxysilyl)propan-1-amine under different conditions. Condensation of pyrimidopyrimidine 3 with thiosemicarbazone derivative gave Schiff base 8, which upon treating with Vilsmeier-Haack reagent afforded pyrazole carbothioamide 9. Cyclocondensation of compound 3 with some binucleophiles namely thiocarbohyrazide, hydrazine carbodithioic acid, benzyl hydrazinecarbodithioate and/or 2-thioxopyrimidinone was investigated. Structures of the new synthesized compounds were confirmed by their analytical and spectral data.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 330792-70-6. Quality Control of 3-Amino-5-(4-phenoxyphenyl)pyrazole-4-carbonitrile.
