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...

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Porous Acidic Catalyst, Functionalized with Imidazole Ionic Liquid ([SBA-Im]HSO4) as a Novel Phase Transfer Catalyst for The Aqueous Synthesis of Benzyl Thiocyanates and Azides
In the present study, application of porous acidic catalyst functionalized with an imidazoleionic liquid ([SBA-Im]HSO4) as a phase transfer catalyst for the facile preparation of benzylthiocyanates and azides in water has been described. The catalyst has been characterized byFourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM), transmissionelectron microscopy (TEM...
متن کاملGraphene oxide as a recyclable phase transfer catalyst.
We demonstrated a simple and green chemical method to obtain Michael adducts and their derivatives by using GO as a phase transfer catalyst with different kinds of bases in water and dichloromethane, and we also used GO multiple cycles almost without reduction in reaction yields.
