Triorganosilanes, which possess two aryl groups on the silicon atom, undergo palladium-catalyzedsilylation of aryliodides. Aryl(2-furyl)silanes thus obtained are potentially useful starting materials for carbon-carbon bond-forming reactions in the presence of transition-metal catalysts and tetrabutylammonium fluoride.

Functional groupexchanges based on single-bond transformation are rare and challenging. In this regard, functional groupexchangereactions of hydrosilanes proved to be more problematic. This is because this exchange requires the cleavage of the C–Si bond, while the Si–H bond is relatively easily activated for hydrosilanes. Herein, we report the first Si–B functional groupexchangereactions of hydrosilanes
