The facile synthesis of functionalized organoboron/silicon compounds by copper-catalyzed coupling of alkylsilyl peroxides and diboron/silylborane reagents is reported. The reactions proceed smoothly under mild, neutral conditions in short reaction times to generate organoboron/silicon compounds bearing a ketone moiety, which are useful synthetic intermediates that are otherwise difficult to access
