strategy to turnover H‐MII‐X complexes has enabled both intra‐ and intermolecular Mizoroki–Heck (MH)‐type reactions of arylcyanides that are challenging to realize under traditional, basic conditions. Initially, a cascade carbonickelation/MH reaction of 2‐cyanostyrenes was achieved using a key alkyne transfer hydrocyanation step. Mechanistic experiments supported the proposed catalytic cycle, including
一种新的转移H-M II - X配合物的转移加氢官能化策略,使芳基氰化物的分子内和分子间Mizoroki-Heck(MH)型反应成为可能,这在传统的基本条件下很难实现。最初,使用关键的炔烃转移氢氰化步骤实现了2-氰基苯乙烯的级联羰基化/ MH反应。机械实验支持了拟议的催化循环,包括促成转移的转移氢氰化步骤。然后将反应性扩展至苄腈和苯乙烯的分子间MH反应。

Two tandem flowchemistry processes have been developed. A single palladium‐catalysed Heck reaction with ethylene gas provides an efficient synthesis for functionalised styrenes. Through further elaboration the catalyst becomes multi‐functional and performs a second Heck reaction providing a single continuous process for the synthesis of unsymmetrical stilbenes. In addition, the continuous, rhodium‐catalysed
We report a palladium-catalysed ethylene Heck reaction for the vinylation of aryl iodides using a tube-in-tube gas-liquid reactor. The flow process afforded various styrenes in short reaction times, employing moderate ethylene pressure.
