Silalactones : The copper‐catalyzed reaction of internal alkynes with (dimethylphenylsilyl)pinacolborane (Me 2 PhSi‐B(pin)) as the silicon source and CO 2 at atmospheric pressure afforded silalactones selectively in good to high yields. The silalactones can be used as substrates for the Hiyama cross‐coupling reaction as demonstrated for one substrate.
