Silicone as a New Class of Organosilicon Reagent for the Palladium-Catalyzed Cross-Coupling Reaction

Abstract
Silicone, polyorganosiloxane, serves as an organosilicon reagent for palladium-catalyzed cross-coupling reactions. Treatment of polymethylphenylsiloxane, poly(alkenyl)methylsiloxane, or cyclic oligosiloxanes with various aryl iodides in the presence of silver(I) oxide or tetrabutylammonium fluoride and a catalytic amount of Pd(0) affords the corresponding coupling product in a good to excellent yield.
