Patent ID: 8232407

Claim:
A compound represented by formula (A), or the optical isomer, cis-trans isomer, or insecticidal acceptable salt thereof, wherein: R 1 is an unsubstituted or halogenated 5 or 6 membered heterocycle interrupted by nitrogen, oxygen and/or sulfur atom(s), or substituted or unsubstituted phenyl, and the substituents are one or more groups selected from halogen atom, C 1-4 haloalkyl and C 1-4 chloroalkoxyl; R 2 is a hydrogen atom, C 1-6 alkyl, or C 1-6 alkyl substituted by fluoro, chloro or bromo; R 3 and R 4 are independently selected from hydrogen atom, C 1-6 alkyl, allyl, benzyl, C 1-4 alkoxyl-C 1-4 alkyl, C 1-4 alkoxyl-carbonyl, phenoxylcarbonyl, C 2-6 alkynyl-carbonyl, C 2-3 alkenyl-carbonyl, C 3-6 cycloalkyl-carbonyl, furan carbonyl, N,N-dimethyl carbonyl, unsubstituted benzoyl or benzoyl substituted by one or more groups selected from halogen atom, C 1-4 alkyl, C 1-4 haloalkyl, C 1-4 alkoxyl, and C 1-4 alkyl-carbonyl, or R 3 and R 4 taken together forms a —CH 2 —CH 2 — or —CH 2 —CH 2 —CH 2 —; R 5 is a hydrogen atom, saturated or unsaturated C 1-6 hydrocarbon group, saturated or unsaturated halogenated C 1-6 hydrocarbon group, or saturated or unsaturated C 1-6 alkoxyl; W is absent, or while R 3 and R 4 taken together forms —CH 2 —CH 2 — or —CH 2 —CH 2 —CH 2 —, W is R 6 which forms onium salt with X − by the nitrogen atom connected with R 6 , wherein R 6 is a hydrogen atom, saturated or unsaturated C 1-6 hydrocarbon group, or saturated unsaturated halogenated C 1-6 hydrocarbon group, or saturated or unsaturated C 1-6 alkoxyl; X − is F − , Cl − , Br − , I − , NO 3 − , SO 4 − , AcO − , or PhCOO − ; Y is a nitro or cyano group; Z is substituted or unsubstituted phenyl, substituted or unsubstituted 5 or 6 membered heterocycle interrupted by nitrogen, oxygen and/or sulfur atom(s), or substituted or unsubstituted C 5-12 heteroaryl, wherein the substituents are one or more groups selected from: halogen atom, nitro, C 1-6 alkyl, hydroxyl C 1-6 alkyl, hydroxyl, C 1-6 alkoxyl, amino, C 1-6 alkylamino, unsubstituted phenyl, or phenyl substituted by one or more groups selected from: halogen atom, C 1-4 alkyl, C 1-4 haloalkyl, C 1-4 alkoxyl, C 1-4 alkyl-carbonyl, C 1-4 alkylamino and C 1-4 alkoxyl-carbonyl.
