Chemistry involves the study of all things chemical – chemical processes, chemical compositions and chemical manipulation – in order to better understand the way in which materials are structured, how they change and how they react in certain situations. , Application In Synthesis of H-Phg-OH, 2935-35-5, Name is H-Phg-OH, molecular formula is C8H9NO2, belongs to phthalazine compound. In a document, author is Eswararao, S., V, introduce the new discover.
1H-pyrazolo[1,2-b]phthalazine-5,10-diones (5) and 2H-indazolo[2,1-b]phthalazine-1,6,11(13H)-triones (7) have been synthesized by one pot, four-component method. To synthesise them phthalic anhydride (1), hydrazine hydrate (2), benzaldehydes (3) and malononitrile (4a) /ethyl cynoacetate (4b) /dimedone (6) in refluxing water for 1-1.5 h in the presence of InCl3 as a catalyst yielding 75-85%. These reactions have an easy workup, provides excellent yields, and uses water as the solvent which is considered to be relatively environmentally benign. The structures of the products were established from their spectral properties IR, H-1-NMR, C-13-NMR & Mass spectroscopy.
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 2935-35-5 is helpful to your research. Application In Synthesis of H-Phg-OH.
