| Abstract: | 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. |
