摘要：

(-)-(S)-t-Butylphenylphosphinothioic acid forms with dialkyl and aralkyl sulfoxides diastereomeric dynamic systems the H-1 NMR spectra of which show typical anisochronism of the diastereotopic S-alkyl groups. The magnetic nonequivalence observed even for delta protons, is great enough to determine the e.e. values of sulfoxides having relatively long alkyl chains (e.g. n-butyl)
