Application of Phase Transfer Catalyst for Synthesizing of 5, 5-diphenylimidazolidine-2,4-dione as a Famous Anticonvulsant Drug
Epilepsy is a major neurological disorder in the world and most epileptics are currently controlled by a variety of drugs. 5, 5-diphenylimidazolidine-2,4-dione (Phenytoin, I) is a widely used antiepileptic drug. It has been synthesized previously by different methods in some solvents. In this work, I was synthesized from the condensation of benzil and urea in ethanol and water by application of...

The interaction of the perimidone drug in solution state with the σ-acceptor iodine, the aliphatic π-acceptor tetracyanoethylene (TCNE) and the aromatic π-acceptor 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) have been studied through the initial formation of ionic intermediate to charge transfer (CT) complex in methanol at room temperature. The spectral studies of the complexes were determi...

Montmorillonite KSF as a very efficient heterogeneous catalyst for the synthesis of 5-substituted 1H-tetrazoles
Montmorillonite KSF has been used as an effective and non-toxic heterogeneous catalyst for one-pot synthesis of 5-substituted 1H-tetrazoles via [3+2] cycloaddition of sodium azide with a wide variety of nitriles. The reaction afforded high yields of the desired products in a short reaction time under mild reaction conditions. The catalyst can be recovered by simple filtration and reuse...
