A description is given of compounds of the formula which in the 4''-position has the (S)-configuration and wherein R1 is C1-C12alkyl, C3-C8cycloalkyl; or C2-C12alkenyl; R2 is hydrogen, optionally substituted C1-C12alkyl or optionally substituted C2-C12alkenyl; R3 is C1-C12alkyl, optionally substituted C1-C12alkyl, optionally substituted C1-C12alkoxy-C1-C12alkyl, optionally substituted C3-C12cycloalkyl, optionally substituted C2-C12alkenyl; optionally substituted C4-C12cycloalkenyl, optionally substituted C2-C12alkynyl; or R2 and R3 together are a three- to seven-membered alkylene or four- to seven-membered alkenylene bridge in each of which a CH2 group may have been replaced by O, S or NR4; X is O or S; R4 is C1-C8alkyl, C3-C8cycloalkyl, C2-C8alkenyl, C2-C8alkynyl, benzyl or C(-O)-R5; R5 is for example H, OH, SH, C1-C12alkyl, C2-C8alkenyl, C2-C8alkynylyl or C1-C12haloalkyl; and, where appropriate, E/Z isomers, mixtures of E/Z isomers and/or tautomers thereof, in each case in free form or in salt form; to a process for the preparation of, and to the use of, such compounds and isomers and tautomers thereof; to starting compounds for the preparation of compounds of formula (I); to pesticidal compositions in which the active ingredient has been selected from the compounds of formula (I) and tautomers thereof; and to a method of controlling pests using such compositions.
