ABSTRACT:
A compound of formula (I); that has the S-configuration at the 4″-position and wherein the bond between carbon atoms 22 and 23 is a single or a double bond; R1is C1-C12alkyl, C3-C8cycloalkyl; or C2-C12alkenyl; R2is H, or, for example, unsubstituted or mono- to penta-substituted C1-C12alkyl, C2-C12alkenyl, C2-C12alkynyl or C1-C6alkoxy-C1-C6alkyl; R3is H or, for example, C1-C12alkyl; X is a bond, O, NR4or S; and Z is C═O, C═S or S02; and, where applicable, E/Z isomers, mixtures of E/Z isomers and/or tautomers, in each case in free form or in salt form; a process for the preparation of and the use of those compounds and their isomers and tautomers; starting materials for the preparation of the compounds of formula (I); pesticidal compositions in which the active ingredient has been selected from those compounds and their tautomers; and a method of controlling pests using those compositions are described.
