Manganese(I)-Catalyzed Asymmetric Hydrophosphination of α,β‑Unsaturated Carbonyl Derivatives

Here we report catalytic asymmetric hydrophosphination of α,β-unsaturated carbonyl derivatives using a chiral Mn­(I) complex as a catalyst. Through H–P bond activation, various phosphine-containing chiral products can be accessed via hydrophosphination of various ketone-, ester-, and carboxamide-based Michael acceptors.
