(R)-(-)-N-(3,5-Dinitrobenzyl)-α-phenylethylamine (I) is an excellent chiral shift reagent for measurement of optical purities of chiral phosphine oxides. The method of preparation and application of reagent I are discussed in detail. 1-Phenyl-3-methyl-2-phospholene(II) is oxidized to 1-phenyl-3-methyl-2-phospholene 1-oxide (III) which is then reacted with tert-BuOOH with complete retention of optical activity. When phosphine oxide is mixed with reagent(I), optical purity of phosphine oxide can be measured according to 1H NMR spectra; the optical purity of II can be determined
