Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics, 1821-12-1, Name is 4-Phenylbutanoic acid, SMILES is O=C(O)CCCC1=CC=CC=C1, belongs to phthalazines compound. In a document, author is Hiremath, Prashant B., introduce the new discover, Category: phthalazines.
Microwave-Accelerated Facile Synthesis of 1H-Pyrazolo[1,2-b]Phthalazine-5,10-Dione Derivatives Catalyzed by WEMPA
An efficient and rapid one-pot multicomponent synthesis of 1H-pyrazolo[1,2-b]phthalazine-5,10-diones through condensation of aldehyde, malononitrile and phthalhydrazide catalyzed by agro-waste solvent catalyst-derived water extract of mango peel ash (WEMPA) under microwave irradiation is described. Further, the catalyst is prepared from agricultural waste and characterized for elemental composition by different techniques such as SEM-EDX, XRD and flame photometry. This green synthetic approach offers various advantages such as inexpensive, abundantly available source, shorter reaction time (6-8 min), good-to-excellent yield (83%-89%), simple workup and a sustainable alternative method to the existing protocols. All the synthesized compounds (4a-l) was confirmed by FT-IR,H-1-NMR,C-13-NMR and LC-MS.
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 1821-12-1 is helpful to your research. Category: phthalazines.
