## Abstract The enantioselective hydrogenation of β‐(acyloxy)‐ and β‐(acylamino)vinylphosphonates with rhodium catalysts based on chiral phosphane‐phosphite ligands has been studied. In the case of the β‐(acyloxy)vinylphosphonates, the reaction also produces an achiral phosphonate resulting from th
