Green Lewis acid catalysis in organic synthesis*
New types of Lewis acids as water-stable catalysts have been developed. Metal salts such as rare earth metal triflates can be used in carbon–carbon bond-forming reactions in aqueous media. These salts can be recovered after the reactions and reused. Furthermore, Lewis acid–surfactant-combined catalysts, which can be used for reactions in water without using any organic solvents, have been also ...
متن کاملsynthesis of 3-aryl-2h-benzo[b]-1,4-oxazines in [omim]bf4 and reduction of organic compounds in methylimidazolium formate
در این پروژه ترکیبات 3-آریل-2h-بنزو[b]-4،1-اکسازین ها از مواد اولیه تجاری مشتقات دو آمینو فنول و ?-هالو کتون های آروماتیک در مایع یونی 1-اکتیل-3-متیل ایمیدازولیوم تترا فلورو بورات([omim]bf4) سنتز شده است. این واکنش توسط باز پتاسیم کربنات محلول از طریق o-آلکیلاسیون و سپس یک واکنش آمیداسیون درون مولکولی خود بخود در مدت زمان کوتاه انجام می شود. ترکیبات 4،1-بنزوکسازین به این روش با بهره خوب تا آلی ...
15 صفحه اولMontmorillonite: An efficient, heterogeneous and green catalyst for organic synthesis
Reactions of organic molecules on Montmorillonite clay mineral have been investigated from various aspects. These include catalytic reactions for organic synthesis, chemical evolution, the mechanism of humus-formation, and environmental problems. Catalysis by clay minerals has attracted much interest recently, and many reports including the catalysis by synthetic or modified clays have been pub...
متن کاملIntroduction to Green Chemistry, Organic Synthesis and Pharmaceuticals
The well being of modern society is unimaginable without the myriad products of industrial organic synthesis. Our quality of life is strongly dependent on, inter alia , the products of the pharmaceutical industry, such as antibiotics for combating disease and analgesics or anti infl ammatory drugs for relieving pain. The origins of this industry date back to 1935, when Domagk discovered the ant...
متن کاملPhase-transfer catalysis. A general green methodology in organic synthesis*
Basic concept of phase-transfer catalysis (PTC), its field of applications and specific features as the most general, efficient, and environment-friendly green methodology of organic synthesis, particularly for industrial processes, is discussed. Organic synthesis is the principal way to produce chemical products of practical applications such as pharmaceuticals, plant protection agents, dyes, ...
