Herein we describe a nickel-catalyzed remote hydrosilylation of unconjugated enones with bulky triphenylsilane. A range of Z-silyl enol ethers are obtained as major isomers due to the process of nickel triggered alkene isomerization. Notably, some specific alkyl silyl enol ethers can be prepared from this protocol, which are not easily accessed by the traditional strategy using a strong base and chlorosilane
在这里,我们描述了一种
镍催化的非共轭烯酮与庞大的三苯基
硅烷的远程氢化
硅烷化。由于
镍引发的烯烃异构化过程,获得了一系列Z-甲
硅烷基烯醇醚作为主要异构体。值得注意的是,可以从该协议中制备一些特定的烷基
硅烯醇醚,而使用强碱和
氯硅烷的传统策略不容易获得这些醚。该反应具有100%原子经济性、反应条件简单、收率好等特点。
