Published: June 2003

Arynes, generated in situ from 2-(trimethylsilyl)aryl triflate and a fluoride ion, were found to insert into a silicon-silicon bond of cyclic disilanes in the presence of a catalytic amount of a palladium-tert-alkyl isocyanide complex to afford diverse benzo-annulated disilacarbocycles straightforwardly in modest to high yields.
