Phosphoroselenoyl chloride bearing a 1,1'-bi-2-naphthyl group was reacted with racemic 2-alkanols to give the corresponding esters. Based on the multiple combination of their NMR spectra, a method for the assignment of the absolute configuration of 1-aryl-2-propanols was established. The solidstate conformations of the esters were confirmed by X-ray structure analyses.
