Cyclic boronates and acetals of mono- and dialkylsubstituted 1,2-, 2,3- 1,3- & 1,4- diols have been quantitatively separated into enantiomers by complexation gas chromatography utilizing optically active metal chelates. An efficient, precise & sensitive method for determining enantiomeric purities for volatile glycols is thus available.
