Phosphine PH3 or H3P CID - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety. A new, mild protocol for deoxygenation of various phosphine oxides with retention of configuration is described. Mechanistic studies regarding the oxygen transfer between the starting phosphine oxide and triphenylphosphine are also presented. Wu, J. Yu, J. Spencer, Org. The phosphine oxides are generally produced as a by-product of the Wittig reaction. What is the driving force in the Wittig reaction? The formation of a phosphine oxide by-product phosphorous wants to form bonds with oxygen rather than carbon The Wittig reaction involves the generation of an ylide intermediate. Phosphoryl refers to a functional group drawn with a phosphorus-oxygen double. Furthermore, it was found that the temperature of the phosphine oxidation significantly influ-enced the yield and the purity of the formed phosphine oxide as it proved very difficult to separate the residual phosphine.
