Novel stereoisomers of N-(R)-(1-arylethyl)-1-alkyl-]2,2-dichlorocyclopropanecarboxamides of the formulae (Ia) and (Ib) …IMAGE… and mixtures thereof,… in which… R1, R2 and X have the meanings given in the description, novel intermediates thereof - the corresponding carboxylic esters, carboxylic acids and carbonyl chlorides - and the use of the stereoisomers or of the mixtures of the compounds of the formulae (Ia) and (Ib) for combating pests. …??Formulae (Ia) and (Ib) provide a general definition of the novel compounds, which can be prepared by analogous processes, for example, from suitable carbonyl chlorides with suitable amines, and, if desired, the mixtures of the stereoisomers can be separated.
