palladium‐catalyzed Catellani‐type reaction using a continuous‐flow platform is described. The implementation of continuous‐flow technology allowed the acceleration of the transformation and, for the first time, expansion of the chemical space to gaseous olefins (i.e., ethylene, propylene and 3,3,3‐trifluoropropene), thus providing a safe and practical approach to sterically hindered ortho‐disubstituted
描述了使用连续流平台的实用均相气液钯催化 Catellani 型反应。连续流技术的实施加速了转化,并首次将化学空间扩展到气态烯烃(即乙烯、丙烯和3,3,3-三氟丙烯),从而提供了安全实用的方法。空间位阻邻位二取代苯乙烯和乙烯基芳烃的方法。事实证明,通过流动技术完全控制气态试剂的化学计量对于指导 Catellani 反应对所需产物的选择性至关重要。
