538-58-9, Name is 1,5-Diphenylpenta-1,4-dien-3-one, belongs to chiral-oxygen-ligands compound, is a common compound. category: chiral-oxygen-ligandsIn an article, once mentioned the new application about 538-58-9.
Condensed Imidazo-1,2,4-triazines. 8. Synthesis of 5H-3,4-Dihydroimidazo<1,2-b>-1,2,4-triazepine Derivatives
2,4,7-Triaryl-5H-3,4-dihydroimidazo<1,2-b>-1,2,4-triazepines were obtained on the basis of 4-phenyl-1,2-diaminoimidazole and chalcones.Their IR, UV, PMR, and mass spectra are discussed.It is shown that the more basic 1-NH2 group of the starting diamine participates in the formation of the azomethine bond of the seven-membered heteroring.The seven-membered ring has a “quasi-boat” form in which the 2- and 4-aromatic substituents occupy equatorial positions.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 538-58-9 is helpful to your research. category: chiral-oxygen-ligands
