This methodology is based on the derivatization of the labile hydrogens of functional groups, such as hydroxyl and carboxyl groups, of olive oil constituents with the phosphorus reagent 2\u2010chloro\u20104,4,5,5\u2010tetramethyldioxaphospholane, and the use of the <jats:sup>31<\/jats:sup>P chemical shifts to identify the phosphitylated compounds. Various experimental aspects such as pertinent instrumentation, sample preparation, acquisition parameters and properties of the phosphorus reagent are reviewed. The strategy to assign the <jats:sup>31<\/jats:sup>P signals of the phosphitylated model compounds and olive oil constituents by employing 1D and 2D NMR experiments is presented. Finally, the capability of this technique to assess the quality and the genuineness of extra\u2010virgin olive oil and to detect fraud is discussed.
