交叉亲电反应是 CC 键形成的一个有前景的策略。最近的研究主要集中在与有机卤化物的反应上。在这里,我们报告了 CN 和 CO 亲电试剂之间的偶联反应,证明了通过 CN 和 CO 裂解构建 CC 键的可能性。已经研究了苄基/芳基铵盐和乙烯基/芳基 CO 亲电试剂之间的几种反应。初步机理研究表明,苄基铵是通过自由基机制活化的。
Cross-Coupling Reactions of Alkenyl Halides with 4-Benzyl-1,4- Dihydropyridines Associated with <i>E</i>

Isomerization under Nickel and Photoredox Catalysis
Cross‐coupling reactions of alkenyl halides with 4‐alkyl‐1,4‐dihydropyridines as alkylation reagents have been achieved by combination of nickel and photoredox catalysts. Alkenyl halides bearing alkyl and aryl substituents are available. Particularly, in the use of aryl‐substituted alkenyl halides, cross‐coupling reactions are associated with E to Z isomerization of alkenes. Thus, Z‐isomers of the
