for rapid reaction screening, a microwave-absorbing solvent is often required in order to achieve efficient reactant heating. In comparison, microreactors can be readily heated and pressurised in order to "super-heat" the reaction mixture, meaning that microwave-transparent solvents can also be employed. To demonstrate the advantages associated with microreaction technology a series of S(N)Ar reactions
虽然微波加热已被广泛证明是用于快速反应筛选的综合有用工具,但通常需要微波吸收溶剂以实现有效的反应物加热。相比之下,微反应器可以很容易地加热和加压以“过热”反应混合物,这意味着也可以使用微波透明溶剂。为了证明与微反应技术相关的优势,按照先前开发的微波协议作为研究的起点,在连续流动下进行了一系列 S(N)Ar 反应。通过这种方法,采用自动化微反应平台 (Labtrix((R)) S1) 在 195 摄氏度和 25 巴下连续流动合成二芳基醚,
