摘要：
Silalactones: The copper-catalyzed reaction of internal alkynes with (dimethylphenylsilyl)pinacolborane (Me 2PhSi-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. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
