diazotization/iododediazotization/cross‐coupling process. The segmented flow stream created by off‐gassing during the Sandmeyer sequence was restored to a continuous column of reaction solution by using a specially designed continuous‐flow unit controlled by custom software created in‐house. The resultant aryl iodide was then combined with a stream of cross‐coupling solution that fed into the final reactor. The system
通过使用伸缩的三反应器流动重氮化/
碘化重氮化/交叉偶联工艺,可以将市售
苯胺转化为联芳基和联芳基
乙炔产品。通过使用由内部定制软件控制的特别设计的连续流装置,将在桑德梅尔序列中由除气产生的分段流动流恢复到反应溶液的连续塔中。然后将生成的芳基
碘化物与交叉偶联溶液流合并,将其送入最终反应器中。该系统被证明是通用的,因为可以快速进行重氮化/
碘化重氮化序列的修饰,以考虑到任何底物特异性(例如,溶解性问题),从而导致了Suzuki–Miyaura和Sonogashira交叉偶联产物的广泛底物范围。
