| abstract | Conversion of an ester of a chiral acid (I) and an optically active alpha-cyano-3-pheroxy-benzyl alcohol (II) having R or racemic R,S configuration or of a non-equimolecular mixt. of the ester of (I) with R configuration (II) and the ester of (I) with S configuration (II) (called "ester (R+S)") to give an ester of the chiral acid (I) with (II) having S configuration. Process is characterised in that the starting esters are treated with a basic agent chosen from ammonia, prim, sec or tert. amines, quat. ammonium derivs, basic ion-exchange resins, high mol. wt. liq. amines and strong bases, which are used in catalytic amts., in a solvent (mixt.) in which the ester of (I) with S configuration (II) is insoluble and the ester for (I) with R configuration (II) is soluble and then isolating the ester of (I) with S configuration (II). Esters of alpha-cyano-3-pheroxy-benzyl alcohol having S configuration and having R configuration with 2,2-dimethyl-3R-(2,2-dichlorovinyl)- cyclopropane-IR-caroxylic acid are new. prods. are useful as Insecticides active against aphids, larvae of lepidoptera, coleoptera, flies, mosquitos etc. The esters of 2,2-dimethyl-3R-(2,2-dihalovinyl)-cyclopropene-IR-carboxylic with S configuration (II) have superior activity to those with R configuration (II). |
