A general route for the synthesis of an aryl(trialkyl)silane reagent, aryl[2-(hydroxypro-2-yl)cyclohexyl]dimethylsilane, is demonstrated. By using a carbonate salt as an activator, the robust aryl(trialkyl)silane promotes nickel-catalyzed aryl–aryl cross-coupling reactions with aryl tosylates in a fluoride-free and highly chemoselective manner. A reusable cyclic silyl ether was also quantitatively recovered.
