synthesis 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 ...

each problem developed, for, as Keele says, "the movement of Leonardo's mind through his life constituted a continuum". Before embarking on his analysis of Leonardo's perception and understanding of the anatomy and physiology of these aspects of Man and Machine, however, Keele considers the general principles of Leonardo's physics in a succinct discussion of his theories of the four elements an...

The concept of wave propagation and the interaction of waves with matter is pivotal in many fields of physics and engineering (e. g. radio transmission, optics, sound propagation, transmission of information in waveguides...). Therefore wave propagation plays a central role in teaching physics, electrical engineering, information technology etc. from the undergraduate level (undergratuate engin...
