A palladium-catalyzed three-component coupling of α-olefins, aryldiazonium salts, and bis(pinacolato)diboron affords direct access to chiral benzylic boronic esters. This process is rendered highly enantioselective using an unprecedented example of cooperative chiralanionphasetransfer and transition-metal catalysis.

show the conversion of unactivated alkenes into α-branched α,β-unsaturated ketones (enones) and esters. Regioselective chloroacylation with acyl chlorides and chloroformates takes place under cooperative nickel/photoredox catalysis. Subsequent HCl elimination provides enones and α,β-unsaturated esters that are not accessible via the conventional acylation approaches that provide the other, linear constitutional
