Abstract:

A series of chiral ferrocenyl diphosphine ligands (ImiFerroPhos ligands) has been applied to the hydrogenation of β-substituted α,β-unsaturated phosphonates to generate a range of optically active β-substituted alkylphosphonates in good yields with good enantioselectivity (up to 92% ee) under mild reaction conditions.

Key words: β-Substituted α,β-unsaturated phosphonate, Asymmetric catalytic hydrogenation, ImiFerroPhos ligands, Rhodium (Ⅱ) complex, Chiral β-substituted alkylphosphonate
