Phosphorylation of 2-Phenyl-4,5-dichloro-3(2H)-pyridazinone with Tributylphosphine. X-ray Diffraction, Spectroscopic, and Quantum-Chemical Study
Phosphorylation of 2-phenyl-4,5-dichloro-3(2H)-pyridazinone was studied and the first C-phosphorylated pyridazinone, 2-phenyl-4-tributylphosphonio-5-hydroxy-3(2H)-pyridazinone chloride, was obtained. The structure of the compound was proved by X-ray diffraction and IR and NMR spectroscopy. The possible reaction pathway was considered from the viewpoint of quantum chemistry.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Electric Literature of 1698-53-9. In my other articles, you can also check out more blogs about 1698-53-9
