<p>A nitrogen-containing heterocyclic compounds are representable by the formula: R3-A-@@-X-R1…… wherein… R1 is either one of the following groups: …<CHEM>… (in which R4 is a hydrogen atom, a halogen atom or a methyl group and @is an integer of 1 or 2);… R2 is a hydrogen atom or a methyl group;… R3 is an alkyl group, an alkoxy group, an alkenyl group or an alkenyloxy group, all of which may have optionally one or more substituents;… A is either one of the following groups:… -CH2-@@-CH2-CH=@@,…… -CH2-@@-CH2-CH2-@@-…… and …<CHEM>… (in which R5, R6, R7, R8 and R9 are, the same or different, each a hydrogen atom or a methyl group,… R10 is a hydrogen atom, a halogen atom or a lower alkyl group and m is an integer of 1 or 4); and… X is an oxygen atom or a sulfur atom, which is useful as an insecticidal agent.</p> |
