Charge transfer complexes of chloranil with drugs
The study of charge transfer (CT) complexes of chloranil with drugs (Naproxen, Nerolin, Methyl anthranilate, Isoxsuprine and Nylidrin) showed that there is a significant interaction between the acceptor and donors as evidenced by colour changes and absorption spectra. From the position of CT bands, the ionization potentials (IPs) of donors were evaluated using appropriate equations. The donor’s...
متن کاملγ-Alumina Nanoparticle Catalyzed Efficient Synthesis of Highly Substituted Imidazoles.
γ-Alumina nano particle catalyzed multi component reaction of benzil, arylaldehyde and aryl amines afforded the highly substituted 1,2,4,5-tetraaryl imidazoles with good to excellent yield in less reaction time under the sonication as well as the conventional methods. Convenient operational simplicity, mild conditions and the reusability of catalyst were the other advantages of this developed p...
متن کاملTransition metal complexes of 2-(substituted-1H-pyrazole-4-yl)-1H- benzo[d]imidazoles: Synthesis and characterization
Four novel monodentate 2-(3′-(4′′-sub-aryl)-1′-phenyl-1H-pyrazole-4-yl)-1H-benzo[d]imidazole ligands (La-d) have been synthesized via the cyclocondensation of o-phenelyndiamine with 1,3-disubstituted pyrazole aldehydes by adding oxidizing agent ceria ammonium nitrate as catalyst in presence of hydrogen peroxide in alcoholic media. The non chelated Cu(II) and Ni(II) complexes of newly synthesize...
متن کاملMechanistic appraisal of the charge-transfer complexes of promethazine with chloranil: a modelling approach.
Various mechanisms are often used to explain the interaction between electron donors and acceptors. Commonly proposed mechanisms are those in which the acceptor interacts with the aromatic pi-systems in the donor molecule or the acceptor forms a weak interaction of the Lewis acid with Lewis base type. In this study, the above mechanisms were examined as well as other possible mechanisms. Promet...
متن کاملNano TiO2@SiO2 as an efficient and reusable catalyst for the synthesis of multi-substituted imidazoles
Nano TiO2 supported on SiO2 (Nano TiO2@SiO2) as a solid Lewis acid, was described to be an effective and reusable catalyst for one-pot three-component reaction of benzil, aryl aldehydes and ammonium acetate for the synthesis 2-aryl-4,5-diphenyl-1H-imdazoles synthesis. To explore the high efficacy of the catalytic system the four-component cyclization of benzil, aryl aldehydes, ammonium acetate ...
