Phosphine oxide (H 3 PO), the first defined compound of phosphorus in the oxidation state −1, was obtained in solution by electrochemical methods starting from white phosphorus (see picture). H 3 PO was characterized by NMR solution spectroscopy as a free molecule and isolated as a ligand in ruthenium(II) complexes following tautomerization to phosphinous acid, H 2 P(OH).
