We report the study of the net donating ability of monodentate and bidentate P ligands stemming from secondary phosphine oxides (SPOs). We experimentally measured and/or calculated the frequencies of CO stretching modes of various metal carbonyl complexes. The inferred electronic properties of the ligands span an unprecedented range, going from π‐accepting phosphite‐like compounds, to extremely electron‐donating ligands outclassing N‐heterocyclic carbenes.
