powerful tool for synthesizing organosilicons. However, chemodivergent synthesis of structurally diverse organosilicons via controllable C–Si bond activation remains challenging. Herein, we report a rhodium-catalyzed chemodivergent synthesis of organosilicons by controllable C–Si bond activation. This protocol enables the rapid synthesis of four types of organosilicons, including allyl silyl ethers
过渡金属催化的 C-Si 键活化已成为合成有机硅的有力工具。然而,通过可控 C-Si 键激活化学发散合成结构多样的有机硅仍然具有挑战性。在此,我们报道了通过可控 C-Si 键激活,铑催化化学发散合成有机硅。该方案能够从简单的硅基炔丙醇和芳基硼酸快速合成四种类型的有机硅,包括烯丙基甲硅烷基醚、乙烯基硅烷、氧杂硅环和β-甲硅烷基酮。成功的关键是控制C-Si键激活的开/关以及不同类型C-Si键的选择性裂解。这项工作证明了过渡金属催化中可控 C-Si 活化的可能性和巨大潜力。
