bis(trimethylsilyl)methyl‐substituted aryl derivatives was prepared by using a Kumada–Corriu cross‐coupling reaction. The regioselective metalation of the resulting bis(trimethylsilyl)methyl‐substituted aryl derivatives bearing this bulky silyl group allowed the generation of functionalized aromatics. A regioselective switch in the presence or in the absence of the bis(trimethylsilyl)methyl group has been
使用Kumada-Corriu交叉偶联反应制备了一系列双(三甲基甲硅烷基)甲基取代的芳基衍生物。带有该庞大甲硅烷基的双(三甲基甲硅烷基)甲基取代的芳基衍生物的区域选择性金属化可以生成官能化的芳族化合物。已经证明了在存在或不存在双(三甲基甲硅烷基)甲基的情况下的区域选择性开关。此外,该甲硅烷基被转化为甲酰基或苯乙烯基,从而扩大了这种双(三甲基甲硅烷基)甲基取代的芳烃的应用范围。
