摘要

PX1018AB The present invention provides compounds of the formula (I): (I) which contains between 9 and 27 carbon atoms, and wherein m and m1 are independently selected from 0, 1 and 2; R2a is hydrogen, methyl, or ethyl; R2b is acetylene or contains between 3 and 18 carbon atoms and is a group R7, wherein R7 is a C1-13. non-aromatic hydrocarbyl group, optionally substituted by a cyano or C1-4 carbalkoxy group and/or by one or two hydroxy groups and/or by one to five halo atoms which are the same or different and/or by one to three groups R8 which are the same or different and each contains one to four hetero atoms, which are the same or different and are chosen from oxygen, sulphur, nitrogen and silicon, 1 to 10 carbon atoms and optionally 1 to 6 fluoro or chloro atoms or R2b is a 6-membered aromatic ring substituted by cyano and/or by one to three groups R8a and/or by a group -C=CH, -C=C-R7a or C=C-halo and/or by one to five halo atoms and/or by one to three C1 4 haloalkyl groups wherein R7a and R8a are groups R7 and R8 as hereinbefore defined; R4 and R6 are the same or different and are chosen from hydrogen, methyl, trifluoromethyl or cyano; R5a is a group wherein R9 is methyl, ethyl, chloro, bromo, methoxy, cyano, nitro, methoxymethyl, C1-4 carbalkoxy or trifluoromethyl, R10 is chloro, methyl or PX1018AB trifluoromethyl or is a group wherein R12 and R13 are both hydrogen, methyl, trifluoromethyl, fluoro, chloro or bromo or R12 is hydrogen and R13 is fluoro, chloro or bromo, or is a three or four membered ring, R9 is oxygen or a group CR14R15 wherein the groups R14 and R15 are the same or different and each is hydrogen, fluoro, chloro or bromo or methyl or ethyl optionally substituted by 1 to 3 fluoro atoms, when is a three membered ring R10 is a group CR14aR15a wherein R14a, R15a are the same or different and each is hydrogen, fluoro, chloro or bromo or methyl or ethyl optionally substituted by 1 to 5 fluoro atoms, or when is a four membered ring R10 is-a group CR14aR15aCR16R17 where; R14a, R15a are as hereinbefore defined, R16, and R17 are the same or different and each is hydrogen, fluoro, chloro or bromo or methyl or ethyl optionally substituted by 1 to 5 fluoro atoms and R11 is hydrogen, methyl, trifluoromethyl, iodo, fluoro, chloro or bromo; and R5b is hydrogen or C1-3 alkyl; provided that R2b is not propyl or butyl and that R5a is not tertiary butyl or tertiary amyl;which are useful pesticides; processes for preparing them, pesticidal formulations containing them and their use in the control of pest infestation.
