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。

towards carboxylic acid addition to the triple bond of terminalalkynes, rather than triple bond addition to the double bond of the enoic acids. To evaluate the results obtained from the carboxylic acid addition reaction of terminalalkynes, the homodimerisation of terminalalkynes (phenylacetylene, 1-octyne, 1-heptyne) was also studied. The homodimerisation of terminalalkynes is found to proceed
