ABSTRACT:
The present invention provides compounds of the formula (I): ##STR1## wherein m and n are independently selected from 0, 1 or 2, ##STR2## R is selected from hydrogen, methyl or ethyl; R.sup.1 is selected from C.sub.1-4 hydrocarbyl substituted by one to five halo atoms, and a group --C.tbd.C--R.sup.9 wherein R.sup.9 is a group S(O).sub.w --R.sup.10 wherein R.sup.10 is trifluoromethyl, methyl or ethyl and w is 0, 1 or 2 or R.sup.9 is a C.sub.3-5 aliphatic group or an aliphatic group containing up to 5 carbon atoms atoms substituted by C.sub.1-4 alkoxy, C.sub.2-6 alkoxyalkoxy, C.sub.1-8 acyloxy, halo or hydroxy, a group COR.sup.11 wherein R.sup.11 is hydrogen, C.sub.1-4 alkyl, C.sub.1-4 alkoxy or a group NR.sup.12 R.sup.13 wherein R.sup.12 and R.sup.13 are independently selected from hydrogen, methyl or ethyl, or R.sup.9 is SiR.sup.14 R.sup.15 R.sup.16 wherein R.sup.14 to R.sup.16 are the same or different and each is a C.sub.1-4 aliphatic group or R.sup.14 and R.sup.15 are C.sub.1-4 aliphatic groups and R.sup.16 is a phenyl group; R.sup.2, R.sup.3, R.sup.7 and R.sup.8 are independently selected from hydrogen, methyl or halo; R.sup.4a and R.sup.4b, R.sup.6a and R.sup.6b are independently selected from hydrogen, C.sub.1-3 alkyl, C.sub.2-3 alkenyl or alkynyl each being optionally substituted by halo, cyano or C.sub.1-4 alkoxy; cyano, halo or a group COR .sup.11a wherein R.sup.11a is hydrogen, C.sub.1-4 alkoxy, C.sub.1-4 alkyl or a group NR.sup.12a R.sup.13a wherein R.sup.12a and R.sup.13a are independently selected from hydrogen, methyl or ethyl; R.sup.5a is a non-aromatic hydrocarbyl group containing up to seven carbon atoms, or phenyl each optionally substituted by cyano, halo, C.sub.1-4 alkyl, C.sub.1-4 haloalkyl, C.sub.3-4 cycloalkyl, C.sub.1-4 alkoxy or a group S(O).sub.q R.sup.17 wherein q is 0, 1 or 2 and R.sup.17 is methyl or ethyl and R.sup.5b is hydrogen, hydroxy or C.sub.1-4 alkyl optionally substituted by alkoxy; and represents --CH--CH-- or --C.dbd.C-- which are useful pesticides, processes for their preparation, pesticidal formulations containing them and their use in the control or prevention of pest infestation.
