Diphenylphosphinophenolate: a ligand for the palladium-catalysed silylation of aryl halides activating simultaneously both palladium and silicon

Diphenylphosphinophenolate was found to be an effective ligand for the pall adium-catalysed silylation of aryl halides, activating not only palladium b ut also silicon of a disilane, where aryl bromides and iodides having such substituents as methyl, methoxy, amino, ethoxycarbonyl, trifluoromethyl, fo rmyl or phenyl are applicable to the reaction with hexamethyldisilane to gi ve the corresponding trimethylsilylarenes.
