Catalytic Silylation: SiO₂-supported gold nanoparticle catalysts showed high activity for silylation of C(sp²)−H bond to afford a series of aryl and heteroarylsilanes. Detailed mechanistic investigation revealed that O₂-activated Au NPs and ethers cooperatively functioned to generate silyl cation, thereby enabling electrophilic C−Si bond formation.
