Synthesis of Alkynylsilanes: A Review of the State of the Art

Abstract

This contribution offers a comprehensive overview of methods for forging sp C–Si bonds. Over time, alkynylsilanes (silylacetylenes), once considered mere byproducts of hydrosilylation processes, have become essential building blocks in organic synthesis. This literature review traces the evolution of their synthesis, from traditional methodologies relying on organolithium and organomagnesium compounds to more advanced cross‐coupling reactions involving hydro‐ and carbosilanes. Focused primarily on the past 25 years (2000‐2024), it also extensively references significant historical breakthroughs. By analyzing synthetic methodologies, the review not only offers a comprehensive survey of the current state of knowledge but also identifies areas for improvement. Furthermore, to emphasize the importance of 1‐alkynylsilanes (1‐silyl‐1‐alkynes), selected applications of these compounds are highlighted, confirming their significant potential in organic synthesis.
