Combination of [Cu(MeCN)4]TFA•TFAH (TFA = O2CCF3) with Feringa's phosphoramidite ligand (LA) provides an exceptionally active (0.75 mol%) catalyst for asymmetric conjugate additions of ZnR2 (R = Et, Me at-40 to-80 o C) to enones. Kinetic and other st... Read More about Mechanistic-Insight-Driven Rate Enhancement of Asymmetric Copper-Catalyzed 1,4-Addition of Dialkylzinc Reagents to Enones.
