the potential of this method remains largely unexplored. Herein, we report a C(sp3)–Si coupling of unactivated alkyl bromides with vinyl chlorosilanes. The reaction proceeds under mild conditions, and it offers a new approach to alkylsilanes. Functionalities such as Grignard-sensitive groups (e.g., acid, amide, alcohol, ketone, and ester), acid-sensitive groups (e.g., ketal and THP protection), alkyl
交叉亲电 C-Si 偶联已成为构建有机硅烷的有前途的工具,但该方法的潜力在很大程度上仍未得到探索。在此,我们报告了未活化的烷基溴与乙烯基氯硅烷的 C(sp 3 )-Si 偶联。该反应在温和的条件下进行,为烷基硅烷的制备提供了一种新方法。官能团,例如格氏敏感基团(例如酸、酰胺、醇、酮和酯)、酸敏感基团(例如缩酮和 THP 保护)、烷基氟和氯化物、芳基溴、甲苯磺酸烷基酯和甲磺酸烷基酯、甲硅烷基醚,和胺是耐受的。证明了-Si(乙烯基)R 2部分与复杂分子的结合以及通过形成的有机硅烷固定玻璃表面。
