Phosphine oxide are typically produced by oxidation of organophosphines. The oxygen in air is often sufficiently oxidizing to fully convert trialkylphosphines to their oxides at room temperature: R3P + 1/2 O2 → R3PO This conversion is usually undesirable. In order to suppress this reaction, air-free techniques … See more Phosphine oxides are phosphorus compounds with the formula OPX3. When X = alkyl or aryl, these are organophosphine oxides. Triphenylphosphine oxide is an example. An inorganic phosphine oxide is phosphoryl chloride See more The deoxygenation of phosphine oxides has been extensively developed because many useful stoichiometric reactions convert tertiary … See more The parent compound phosphine oxide (H3PO) is unstable.
