Copper(II) triflate immobilized in [bmim]BF4 ionic liquid: An efficient reaction medium for Michael addition of beta-ketoesters to acceptor-activated alkenes
1,3-Dicarbonyl compounds undergo smooth conjugate addition to alpha,beta-unsaturated ketones in the presence of 10 mol % copper(II) triflate immobilized in air and moisture stable [bmim]BF4 ionic liquid under extremely mild conditions to afford the corresponding Michael adducts in high to quantitative yield.
