Highly regio- and stereoselective hydrosilylation applicable to a broad range of electron-deficient alkynes has been established using palladium catalysis. The synthetic utility of the method has been demonstrated by further transformations of α-silylalkenes, particularly Hiyama coupling and stereoinverting iododesilylation followed by Suzuki–Miyaura coupling, which enables stereodivergent syntheses
使用钯催化已经建立了适用于多种缺电子炔烃的高度区域选择性和立体选择性氢化硅烷化。该方法的合成效用已通过α-甲硅烷基烯烃的进一步转化,特别是Hiyama偶联和碘代甲硅烷基化的立体转化,再加上Suzuki-Miyaura偶联得以证明,这使得α-芳烯酸酯能够立体发散。
