Synthesis of Unsymmetrical Biaryls by Palladium-Catalyzed Cross Coupling Reactions of Arenes with Tetrabutylammonium Triphenyldifluorosilicate, a Hypervalent Silicon Reagent.
Palladium-catalyzed cross coupling of arenes with tetrabutylammonium triphenyldifluorosilicate, a hypervalent silicon reagent, to give unsymmetrical biaryls is reported. The Pd(0)-catalyzed process proceeds in good yield with aryl iodides, most aryl triflates, and electron-deficient aryl bromides.
