Abstract
Abstract (R)-(−)-N-(3,5-dinitrobenzoyl)-α-phenylethylamine is a chiral shift reagent which allows ee measurements of various phosphine oxides. Good results were obtained for monophosphine oxides with asymmetric phosphorus centers as well as with an asymmetric carbon in α position of phosphorus. The reagent is also able to differentiate the two enantiomers of racemic DIOP dioxide.
