An enantioselective copper-catalyzed borylacylation of aryl olefins with acyl chlorides and bis-(pinacolato)diboron proceeds with a 2 mol % catalyst loading and is generally completed within 30 min at room temperature. The resulting chiral β-borylated ketones are versatile intermediates in organic synthesis.
