The signature reactivity of silacyclobutane (SCB) is their cycloaddition reactions with various π bonds. Recently, the first cases were disclosed where SCBs reacted with both Csp2−H and Csp3−H σ bonds in an intramolecular fashion. Herein, it is reported that SCB is also an efficient reagent for Csp−H bond silylation. Thus, rhodium‐catalyzed intermolecular reactions between SCBs and terminal alkynes
