WebFeb 14, 2012 · Air oxidation leads to a mixture of products due to the insertion of oxygen into one or more P-C bonds. (31)P NMR spectroscopy in solution and in the solid state, as well as IR spectroscopy reveal distinct features of the phosphine oxides as compared to their H(2)O(2) adducts.

Phosphine oxide - Wikipedia

Phosphine oxides are ligands in various applications of homogeneous catalysis. In coordination chemistry, they are known to have labilizing effects to CO ligands cis to it in organometallic reactions. The cis effect describes this process. 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 Phosphine oxide are typically produced by oxidation of organophosphines. The oxygen in air is often sufficiently oxidizing to fully convert … See more The parent compound phosphine oxide (H3PO) is unstable.
