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. , Recommanded Product: 618-88-2, 618-88-2, Name is 5-Nitroisophthalic acid, molecular formula is C8H5NO6, belongs to phthalazine compound. In a document, author is Reddy, Y. Dathu, introduce the new discover.
One-pot, four component syntheses for the preparation of 1-H Pyrazolo[1,2-b]phthalazine-5,10-diones (5a-5h) and 2H-indazolo[2,1-b]phthalazine-1,6,11(13-H)-triones (7a-7f) have been described from phthaloyl dichloride (1), hydrazine hydrate (2), benzaldehydes (3) and malononitrile (4a), ethyl cynoacetate (4b) or dimedone (6) in refluxing water for 1-1.5 h by in-situ generation of HCl as a catalyst. These reactions have easy workup, provide excellent yields, and use water as the solvent.
