CYCLOPROPANECARBOXYLIC-ACID DERIVATIVES, THEIR PREPARATION, THEIR USE AS PARASITICIDES AND COMPOSITIONS CONTAINING THEM

摘要

Novel cyclopropanecarboxylates in all possible isomeric forms or mixtures thereof of the formula I with a 1R,cis or 1R,trans structure and wherein X is a halogen, R is selected from the group consisting of (A) optionally unsaturated alkyl of 2 to 12 carbon atoms, (B) optionally unsaturated cycloalkyl of 3 to 12 carbon atoms, (c) Z is selected from the group consisting of -C 3BOND CH, -CH3 and -CN and Ar is selected from the group consisting of -C6H5, -C6F5, +TR B is hydrogen or fluorine and X is fluorine, chlorine or bromine (D) (E) and (F) Y2 is selected from the group consisting of hydrogen, fluorine, chlorine bromine, -C 3BOND N and -C 3BOND CH, Y3, Y4, and Y5 are individually selected from the group consisting of hydrogen, fluorine, chlorine, bromine alkyl of 1 to 8 carbon atoms and cycloalkyl of 3 to 8 carbon atoms optionally substituted by one or more functional groups, alkenyl of 2 to 8 carbon atoms and alkynyl of 2 to 8 carbon atoms, and two of Y3, Y4 and Y5 can form rings between them with the proviso that if X is bromine and R is and Z is cyano or ethynyl and Ar is the carbon carrying Z is in the (S) configuration and the double bond in the 3-side chain may have E or Z structure useful in combatting pests such as insects, nematodes acarids.
