Selective long-distance isomerization of terminal alkenes to silyl enol ethers proceeded via nondissociative chain walking using phenanthroline palladium catalysts. Notable features achieved taking advantage of the nondissociative chain walking mechanism include high efficiency obtained regardless of the chain length, high chemoselectivity toward terminal alkenes over internal ones, and retention of
末端烯烃向甲硅烷基烯醇醚的选择性长距离异构化是通过使用菲咯啉钯催化剂的非解离链走进行的。利用非解离链行走机制获得的显着特征包括无论链长如何都获得了高效率,相对于内部烯烃对末端烯烃的高化学选择性以及在烷基链上保留了立体中心的立体构型。
