Abstract

The invention relates to novel compounds of the formula (I)

in which the R 1 , R 2a , R 2b , R 3 , A 1 , A 2 , A 3 , A 4 and n radicals are each as defined above,
to their use as acaricides and/or insecticides for controlling animal pests and to processes and intermediates for their preparation.

First claim

The invention claimed is:

1. A compound of formula (I),

wherein
A 1 represents nitrogen,
A 2 represents N—R 5 ,
A 3 represents oxygen,
A 4 represents=C—H,
R 1 represents methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl or tert-butyl,
R 2a represents hydrogen,
R 2b represents one of the following radicals:

R 3 represents fluoromethyl, difluoromethyl, trifluoromethyl, fluoroethyl, difluoroethyl, trifluoroethyl, tetrafluoroethyl or pentafluoroethyl,
R 5 represents methyl, ethyl or isopropyl, and
n represents 2.

2. The compound of formula (I) according to claim 1 , wherein
A 1 represents nitrogen,
A 2 represents —N—R 5 ,
A 3 represents oxygen,
A 4 represents ═C—H,
R 2a represents hydrogen,
R 2b represents one of the following radicals:

n represents 2,
R 1 represents ethyl,
R 3 represents trifluoromethyl or pentafluoroethyl, and
R 5 represents methyl.

3. An agrochemical formulation comprising one or more compounds of formula (I) according to claim 1 and one or more extenders and/or surfactants.

4. The agrochemical formulation according to claim 3 , additionally comprising a further agrochemically active compound.

5. A method for controlling animal pests, wherein the one or more animal pests are selected from the group consisting of insects, arachnids, helminths, nematodes, and molluscs, comprising allowing a compound of formula (I) according to claim 1 or an agrochemical formulation thereof to act on one or more animal pests and/or a habitat thereof.

6. A product comprising a compound of formula (I) according to claim 1 or an agrochemical formulation thereof for controlling animal pests.

7. The compound of formula (I) according to claim 2 , wherein
R 3 represents pentafluoroethyl, and
R 5 represents methyl.

8. The compound of formula (I) according to claim 7 , wherein
R 2b represents

9. The compound of formula (I) according to claim 1 , wherein
R 1 represents ethyl,
R 3 represents trifluoromethyl, and
R 5 represents methyl.

10. A method for controlling animal pests, wherein the one or more animal pests are selected from the group consisting of insects, arachnids, helminths, nematodes, and molluscs, comprising allowing a compound of formula (I) according to claim 8 or an agrochemical formulation thereof to act on one or more animal pests and/or a habitat thereof.

11. A method for controlling animal pests, wherein the one or more animal pests are selected from the group consisting of insects, arachnids, helminths, nematodes, and molluscs, comprising allowing a compound of formula (I) according to claim 9 or an agrochemical formulation thereof to act on one or more animal pests and/or a habitat thereof.
