 Organosilicon compounds successfully synthesized via the Wurtz–Fittig reaction include silylated calixarenes, "t-"Butylsilicon compounds, and vinylsilanes.For example, "t"-butyltriethoxysilane can be prepared via the Wurtz–Fitting reaction by combining tetraoxysilane, "t"-butyl chloride and molten sodium.The reaction proceeds with a 40% yield.
