The palladium-catalyzed cross-coupling of 2-allylphenyl triflate and related electrophiles with substituted indenes affords biindene derivatives in moderate to good yields with high selectivity for thermodynamically preferred alkene isomers. The transformations involve alkene nucleopalladation with indenyl anions, and we also demonstrate that 2-allylphenyl triflates can be transformed to indenes under
2-烯丙基苯基三氟甲磺酸酯和相关亲电子试剂与取代茚的钯催化交叉偶联以中等至良好的产率提供联茚衍生物,并且对热力学优选的烯烃异构体具有高选择性。该转化涉及烯烃与茚基阴离子的核钯化,我们还证明了 2-烯丙基苯基三氟甲磺酸酯可以在类似条件下转化为茚。描述了这种转化的范围以及茚和联茚产物的形成机制。
