palladium-catalyzed carbonylative Heck reaction of aryl thianthrenium salts with carbon monoxide and alkenes has been developed. This protocol can greatly reduce the quantity of olefins used in the carbonylative Heck reaction. In addition, the reaction can also proceed when the coupling partner is a non-activated olefin which is not common in such carbonylative Heck reactions. Combined with C–H thianthrenation
在此,开发了一种有效的钯催化的芳基铊盐与一氧化碳和烯烃的羰基化 Heck 反应。该方案可以大大减少羰基化Heck反应中使用的烯烃的量。此外,当偶联配对物是在此类羰基化Heck反应中不常见的非活化烯烃时,该反应也可以进行。结合芳烃的C-H噻嗪化反应,该工作为芳烃的位点选择性C-H羰基化Heck反应提供了一种有效的方法。它可能作为未来复杂分子修饰的重要后期羰基化工具。
