Phospholene oxide
WebPhosphine Oxides are normally classified as primary, secondary and tertiary oxides generally represented by the formula RPH2(O), R2PH(O) and R3P=O. The phosphine oxides are generally produced as a by-product of the Wittig reaction. Tertiary phosphine oxides are more stable than the primary and secondary phosphine oxides, and therefore least …
