A synthetic methodology for a tailored design of functional siloxanes is presented. We show that by incorporating molecular scissors into the siloxane framework, the Si−O−Si linkage can easily be cleaved at a desired position and siloxy groups exchanged for one another. The method allows also for a direct one-step cleavage of chlorosiloxanes and shows broad substrate scope, high variability of functional
提出了一种定制设计功能性硅氧烷的合成方法。我们表明,通过将分子剪刀合并到硅氧烷骨架中,Si−O−Si 连接可以很容易地在所需位置断裂,并且硅氧基团可以相互交换。该方法还可以直接一步裂解氯硅氧烷,并显示出广泛的底物范围、功能性硅氧基单元的高度可变性和优异的选择性。
