Copper‐Catalyzed Borylacylation of Activated Alkenes with Acid Chlorides

A method for Cu-catalyzed borylacylation of activated alkenes is presented. The reaction involves the borylcupration of the alkene followed by capture of the generated alkyl-Cu intermediate with an acid chloride. The reactions operate with low catalyst loading and generally occur within 15 min at room temperature for a range of activated alkenes. In the case of vinyl arenes, enantioselective borylacylation can be carried out.
