The catalytic C–H silylation of sulfides with hydrosilanes is of much interest and importance but has remained unexplored to date. We report here the C–H silylation of methyl sulfides with hydrosilanes by an yttrium metallocene catalyst. The reaction took place regioselectively at the α-methyl C–H bond, affording the corresponding silylated sulfide derivatives that are difficult to make by other means
硫化氢与氢硅烷的催化C–H甲硅烷基化是非常令人感兴趣和重要的,但迄今为止尚未开发。我们在这里报告了钇金属茂催化剂将甲基硫化物与氢硅烷的C–H甲硅烷基化反应。该反应在α-甲基CH键上进行区域选择性反应,得到相应的甲硅烷基化的硫化物衍生物,很难用其他方法制备。
