as a convenient and versatile inline analytical tool for Grignard formation in continuous flow chemical processing. The LiCl-mediated halogen/Mg exchange reaction was used for the preparation of functionalized arylmagnesium compounds from aryl iodides or bromides. Furthermore, inline IR monitoring was used for the analysis of conversion and possible byproduct formation, as well as a potential tool for
新开发的微型ReactIR流通池被用作方便且通用的在线分析工具,用于在连续流式化学过程中形成格氏试剂。LiCl介导的卤素/ Mg交换反应用于由芳基碘化物或溴化物制备官能化的芳基镁化合物。此外,在线IR监测用于分析转化率和可能的副产物形成,以及用于阐明机理细节的潜在工具。本文所述的结果表明,由于快速混合和有效的热传递,连续流系统对于高度放热的反应如格利雅交换反应是有效的。
