Dealkynative Coupling: C−H silylation of several terminal acetylenes has been established by using sustainable and eco-friendly main-group catalysis. As a result, several alkynes, including pharmaceuticals, were selectively silylated under transition metal-free conditions. Mechanistic studies provided strong support for the deprotonation step, which is followed by the formation of pentacoordinated
Dealkynative Coupling:通过使用可持续和环保的主基团催化,已经建立了几种末端乙炔的 C-H 硅烷化。结果,包括药物在内的几种炔烃在无过渡金属条件下被选择性甲硅烷基化。机理研究为去质子化步骤提供了强有力的支持,随后形成五配位硅物种。
