conveyor has been described. This reaction provides an efficient route to construct diverse polycyclic frameworks in moderate to good yield via palladium-catalyzed remote C-H activation/alkene insertion, arylation, alkenylation, and the Heck reaction. The preliminary mechanistic studies revealed that the 1,4-palladium migration process was reversible.
已经描述了空前的分子内远程CH活化,其通过以芳香环作为传送带的连续1,4-钯迁移来实现。该反应提供了一种有效的途径,可通过钯催化的远程CH活化/烯烃插入,芳基化,烯基化和Heck反应,以中等到良好的产率构建各种多环骨架。初步的机理研究表明,1,4-钯的迁移过程是可逆的。
