Asymmetric α‐Alkylation With Activated and Unactivated Electrophiles by a Highly Productive and Recyclable Lewis Acid/Imidazolium Catalyst

Angewandte Chemie International Edition, EarlyView.
An air‐stable, easily prepared, bifunctional Cu(II)/imidazolium complex enables highly enantioselective α‐alkylation of 1,3‐dicarbonyls with outstanding productivity (TON up to 1740).
