Microwave Assisted Synthesis of N-Substituted-7-hydroxy-4-methyl-2-oxoquinolines as Anticonvulsant Agents

E-Journal of Chemistry, 2011
The reaction of resorcinol with ethylacetoacetate yielded the 7-hydroxy-4-methyl coumarin (1), which on treatment with benzidine gives 1-(4ʹ-amino-biphenyl-4-yl)-7-hydroxy-4-methyl-1H-quinolin-2-one (2). 1-{4ʹ-[(Substituted benzylidene)-amino]-biphenyl-4-

A Mild and Practical Synthesis of Biphenyl Compounds

Journal of Chemical Research, 2012
A mild and practical synthetic route for biphenyls is established. Isopropyl nitrite was prepared from sodium nitrite, isopropanol and hydrochloric acid. The biphenyl compounds were obtained from the diazotisation of aniline derivatives with the generated isopropyl nitrite and the coupling reaction with benzene derivatives in the presence of CuCl as a ...

Synthesis and Optical Properties of a Biphenyl Compound

Walailak Journal of Science and Technology, 2013
In this work the synthesis of a biphenyl compound (BPHD) [2,2(biphenyl-4-4-diylbis (azan-1-yl-1-ylidene)bis(methan-1-yl-1-ylidene)diphenol], was characterized by FTIR spectroscopy and CHN analysis. Then optical absorption of single crystals were measured. Thin films were deposited by spin-coating. Transmittance measurements in the wavelength range (190
