Abstract

A compound of formula (I): wherein R¹ is pyrid-4-yl optionally substituted by one to four substituents independently selected from halogen, C_1-3 alkyl or C_1-3 haloalkyl; R² is hydrogen, halogen, C_1-4 haloalkyl or C_1-4 haloalkoxy; R³ is trifluoromethyl, difluoromethyl or difluoromethoxy and R⁴ is hydrogen, fluoro or chloro, or R³ is fluoro, chloro or bromo and R⁴ is fluoro, chloro or trifluoromethyl; and R⁵ is hydrogen or halogen; or salts or N-oxides thereof. Furthermore, the present invention relates to intermediates used to prepare compounds of formula (I), to methods of using them to combat and control insect, acarine, mollusc and nematode pests and to insecticidal, acaricidal, molluscicidal and nematicidal compositions comprising them.

Claims

1. A compound of formula (I)

2. A compound according to claim 1 wherein R¹ is pyrid-4-yl optionally substituted by one to four substituents independently selected from fluoro, chloro, bromo, methyl, difluoromethyl, chlorodifluoromethyl or trifluoromethyl.

3. A compound according to claim 1 wherein R² is hydrogen, fluoro, chloro, bromo, trifluoromethyl, pentafluoroethyl, trifluoromethoxy, 2,2,2-trifluoroethoxy, or 1,1,2,2-tetrafluoroethoxy.

4. A compound according to any preceding claim wherein R⁵ is hydrogen, fluoro or chloro.

5. A compound of formula (II)

6. A method of combating and controlling insects, acarines, molluscs or nematodes which comprises applying to a pest, to a locus of a pest, or to a plant susceptible to attack by a pest an insecticidally, acaricidally, molluscicidally or nematicidally effective amount of a compound of formula (I) as defined in claim 1.

7. An insecticidal, acaricidal, molluscicidal or nematicidal composition comprising an insecticidally, acaricidally, molluscicidally or nematicidally effective amount of a compound of formula (I) as defined in claim 1.
