palladium-catalyzed remote 1,n-arylamination (from 1,3- to 1,11-arylamination) of unactivated terminal alkenes with aryl iodides and arylamines has been realized. This three-component reaction proceeded via Pd-catalyzed Heck arylation, alkene isomerization, and aza-Michael addition, exhibiting good regio- and chemoselectivity, and wide substrate scope. Preliminary mechanistic studies indicated that the
已经实现了未活化的末端烯烃与芳基碘化物和芳基胺的钯催化的远程1,n-芳基化(从1,3-至1,11-芳基化)。该三组分反应是通过Pd催化的Heck芳基化,烯烃异构化和aza-Michael加成反应进行的,具有良好的区域选择性和化学选择性,并具有较宽的底物范围。初步的机理研究表明,原位生成的邻/对苯醌甲基化物中间体可作为烯烃异构化的驱动力,并促进亲核胺化反应后的重新芳构化。
