Name: 2-Oxo-2-phenylacetic acid, As a society publisher, everything we do is to support the scientific community – so you can trust us to always act in your best interests, and get your work the international recognition that it deserves. 611-73-4, Name is 2-Oxo-2-phenylacetic acid, SMILES is O=C(O)C(C1=CC=CC=C1)=O, belongs to phthalazine compound. In a article, author is Eswararao, S., V, introduce new discover of the category.
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.
