Abstract

PURPOSE:To measure accurately and simply with high resolution the ratio of an optical isomer in a compound that contains a functional group of Lewis base by nuclear magnetic resonance method with the addition of a compound that has other functional group of Lewis base under the existence of a specific optical activity shift reagent. CONSTITUTION:When the ratio of an optical isomer of a compound that has functional groups of Lewis base such as OH, SH, NH2, CN, etc. is analysed by nuclear magnetic resonance method, using a shift reagent of optical activity as represented by the formula, a compound of alcohol, amine or others that has a functional group of Lewis base which is different from said object compound to be measured as the third component. With this set-up the ratio of optical isomers such as alpha-cyano-3-pheoxybenzil alcohol, etc. which are not sufficiently separable or inseparable can be analysed simply with high resolution.
