An electrochemically-driven enantioselective nickel-catalyzed reductive cross-coupling of alkenyl bromides and benzylchlorides is reported. The reaction forms products bearing allylic stereogenic centers with good enantioselectivity under mild conditions in an undivided cell. Electrochemical activation and turnover of the catalyst mitigate issues posed by metal powder reductants. This report demonstrates

the reaction. This new alkenylation protocol has been successfully demonstrated in direct modification of naturally occurring complex acids and is amenable to the enantioselective decarboxylative alkenylation of arylacetic acid. Mechanistic studies, including a series of controlled experiments and cyclic voltammetry data, allow us to probe the key intermediates and the pathway of the reaction.
2-Bromo-1-alkenes are cleanly and conveniently generated in good yields and selectivities via microwave-assisted hydrobromination of 1-alkynes using a combination of lithium bromide (LiBr), chlorotrimethylsilane (TMSCl), and tetraethylammonium bromide (TEAB) in acetonitrile (MeCN).
