  The cross-electrophile reaction is a promising strategy for C-C bond formation. Recent studies have focused mainly on reactions with organic halides. Here we report a coupling reaction between C-N and C-O electrophiles that demonstrates the possibility of constructing a C-C bond via C-N and C-O cleavage. Several reactions between benzyl/aryl ammonium salts and vinyl/aryl C-O electrophiles have been

  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。
