Abstract

Reactions of the tertiary phosphines R3P (R= Me, Bu, Oct, Cy, Ph) with 35% aqueous H2O2 gives the corresponding oxides as the H2O2 adducts R3PO·(H2O2) x (x= 0.5–1.0). Air oxidation leads to a mixture of products due to the insertion of oxygen into one or more P–C bonds. 31P 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 H2O2 adducts. The ...
