ABSTRACT:
Novel esters in all possible isomeric forms and mixtures thereof of the formula ##STR1## wherein R is selected from the group consisting of (a) optionally unsaturated alkyl of 1 to 18 carbon atoms and optionally unsaturated cycloalkyl or cycloalkylalkyl of 3 to 8 carbon atoms optionally substituted with at least one member of the group consisting of halogen, --OH, --SH, --OR', --SR', --NO.sub.2, ##STR2## --SO.sub.2 AlK.sub.2, --SO.sub.3 AlK.sub.3, aryl optionally substituted with at least one member of the group consisting of --OH, alkoxy of 1 to 8 carbon atoms, alkyl of 1 to 8 carbon atoms, halogen, --CF.sub.3, --OCF.sub.3, --SCF.sub.3 and ##STR3## R' is alkyl of 1 to 8 carbon atoms, R" and R'" are individually selected from the group consisting of hydrogen and alkyl of 1 to 8 carbon atoms, AlK.sub.1, AlK.sub.2 and AlK.sub.3 are individually alkyl of 1 to 18 carbon atoms (b) aryl of 6 to 14 carbon atoms optionally substituted with at least one substituent selected from the group consisting of --OH, alkoxy of 1 to 8 carbon atoms, alkyl of 1 to 8 carbon atoms, halogen, --OCF.sub.3, --CF.sub.3 and --SCF.sub.3 and (c) heterocycle optionally substituted with at least one member of the group consisting of --OH, alkoxy of 1 to 8 carbon atoms, alkyl of 1 to 8 carbon atoms, halogen, --CF.sub.3, --OCF.sub.3 and --SCF.sub.3, A is selected from the group consisting of optionally unsaturated alkyl of 1 to 18 carbon atoms, optionally unsaturated cycloalkyl of 3 to 18 carbon atoms and the remainder of an alcohol used in synthesis of pyrethrinoid esters, X is halogen and the ethylenic double bond may have Z or E geometry having antiparasitic activity, especially insecticidal, acaricidal and nematocidal activity.
