Readily available copper precatalysts, (NHC)CuOtBu (NHC = N-heterocyclic carbene), catalyze dehydrogenative borylation and silylation of styrenes with moderate to high yields, using ketone additives as sacrificial oxidants. This method provides access to trisubstituted vinylboronates and vinylsilanes without requiring noble metal catalysis.
