53-89% yield, 69-96% SN2″ selectivity, 98:2 to >98:2 E: Z ratio, and 94:6-98:2 er. Insight regarding several of the unique mechanistic attributes of the catalytic process was obtained on the basis of kinetic isotope effect measurements and DFT studies. These investigations indicate that cationic π-allyl-Cu complexes are likely intermediates, clarifying the role of the s-cis and s-trans conformers of
