Zusammenfassung:	A substantially pure compound selected from the group consisting of the d-menthyl esters of 1RS-cis-, 1RS-cis/trans-, 1R-cis-, 1S-cis-, 1R-trans- and 1S-trans-3-(2,2-dichloro- and dibromo-vinyl)-2,2-dimethylcyclopropanecarboxylic acid, the 1-menthyl esters of 1RS-cis-, 1RS-trans-, 1RS-cis/trans-, 1R-cis-, 1S-cis-, 1R-trans- and 1S-trans-3-(2,2-dibromo-vinyl)-2,2-dimethyl-cyclopropanecarboxylic acid and the 1-menthyl esters of 1R-trans- and 1S-trans-3-(2,2-dichloro-vinyl)-2,2-dimethyl-cyclopropanecarboxylic acid. The esters are produced by reacting enantiomers of the acids with d- or 1-menthol are selectively crystallizing.
