在降冰片烯(Norbornene)与Pd协同催化下,芳基碘化物先和降冰片烯进行Heck反应,接着邻位C-H活化进行烷基化或芳基化,最后再和端基烯烃偶联得到邻位取代的烯基芳烃的反应。此反应是三组分偶联反应。邻位单取代的芳基碘化物作为底物则可以得到不同邻位取代基的烯基芳烃。
该反应中生成了五元钯环中间体(下图机理中的3),可以在卤素邻位引入亲电试剂,接着在原位通过Mizoroki-Heck反应、Suzuki-Miyaura反应、Buchwald-Hartwig反应等实现芳烃的双官能团化。
1997年意大利化学家Catellani首次报道了此反应,因此也由其名字命名。
反应机理
Pd在催化循环中分别经历了0・II・IV价态。在苯环邻位C-H活化阶段,首先是反应性较高的降冰片烯进行插入,拉近了Pd与邻位C-H的距离后完成的整个催化循环。最近计算化学再次验证解释了其具体反应机理(Catellani M. et al, J. Am. Chem. Soc. 2011, 133, 8574. DOI:10.1021/ja110988p )
