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

In this work, an efficient method for the copper-catalyzed ring-opening hydrolysis of silacyclobutanes to silanols was developed. This strategy has the advantages of friendly reaction conditions, simple operation, and good functional group compatibility. No additional additives are required in the reaction, and the S–S bond can also be introduced into the organosilanol compounds in one step. Furthermore
