to high enantioselectivity relies on two distinct ligands that act cooperatively: an exogenous monodentate chiral phosphite that induces enantioselectivity and an endogenous acetylacetonate that exerts a remarkably positive influence on the enhancement of enantioselectivity. Detailed experimental and computational studies elucidate the effect of ligand cooperativity and the key steps involving σ-bond
