Novel heterocyclic pesticidal compounds.

摘要

The present invention provides compounds of the formula (I): <CHEM> wherein m and n are independently selected from 0, 1 or 2, <CHEM> R is selected from hydrogen, methyl or ethyl; R<1> is selected from C1-4 hydrocarbyl substituted by one to five halo atoms, and a group -C IDENTICAL C R<9> wherein R<9> is a group S(O)w R<1><0> wherein R<1><0> is trifluoromethyl, methyl or ethyl and w is 0, 1 or 2 or R<9> is a C3-5 aliphatic group or an aliphatic group containing up to 5 carbon atoms substituted by C1-4 alkoxy, C2-6 alkoxyalkoxy, C1-8 acyloxy, halo or hydroxy, a group COR<1><1> wherein R<1><1> is hydrogen, C1-4 alkyl, C1-4 alkoxy or a group NR<1><2>R<1><3> wherein R<1><2> and R<1><3> are independently selected from hydrogen, methyl or ethyl, or R<9> is SiR<1><4>R<1><5>R<1><6> wherein R<1><4> to R<1><6> are the same or different and each is a C1-4 aliphatic group or R<1><4> and R<1><5> are C1-4 aliphatic groups and R<1><6> is a phenyl group; R<2>, R<3>, R<7> and R<8> are independently selected from hydrogen, methyl or halo; R<4a> and R<4b>, R<6a> and R<6b> are independently selected from hydrogen, C1-3 alkyl, C2-3 alkenyl or alkynyl each being optionally substituted by halo, cyano or C1-4 alkoxy; cyano, halo or a group COR<11a> wherein R<11a> is hydrogen, C1-4 alkoxy, C1-4 alkyl or a group NR<12a> R<13a> wherein R<12a> and R<13a> are independently selected from hydrogen, methyl or ethyl; R<5a> is a non-aromatic hydrocarbyl group containing up to seven carbon atoms, or phenyl each optionally substituted by cyano, halo, C1-4 alkyl, C1-4 haloalkyl, C3-4 cycloalkyl, C1-4 alkoxy or a group S(O)q R<1><7> wherein q is 0, 1 or 2 and R<1><7> is methyl or ethyl and R<5b> is hydrogen,hydroxy or C1-4 alkyl optionally substituted by alkoxy; and .... represents -CH-CH- or -C=C- which are useful pesticides, processes for their preparation, pesticidal formulations containing them and their use in the control or prevention of pest infestation.
