Electric Literature of 88-99-3, The transformation of simple hydrocarbons into more complex and valuable products via catalytic C–H bond functionalisation has revolutionised modern synthetic chemistry. 88-99-3, Name is Pathalic acid, SMILES is O=C(O)C1=CC=CC=C1C(O)=O, belongs to phthalazine compound. In a article, author is Linko, R. V., introduce new discover of the category.
10-(1-Phthalazinylazo)-9-phenanthrol (HL, I) was synthesized by the reaction between 1-hydrazinophthalazine and 9,10-phenanthrenequinone. The crystal and molecular structures of compound I were determined by X-ray diffraction (XRD). According to XRD, EAS, and H-1 and C-13 NMR data, a HL molecule in solutions and in crystals exists in the form of quinohydrazone tautomer (b) (s-trans, cis) stabilized by intramolecular N(3)H…O(1) hydrogen bond. The mobile H atom is localized at the N(3) atom of the azo group. The phthalazine (A) and phenanthrenequinone (B) moieties of the HL molecule are nearly coplanar. The HL basicity and acidity constants (pK(a) = 1.90 and pK(a) = 11.65, respectively) and the formation constants of HL complexes with Zn2+ and Cd2+ and their compositions in solutions were determined. ML2 center dot DMFA complexes, where M = Zn2+, Cd2+, were synthesized. The coordination mode of the L- ligand with metal atoms was suggested.
