- the cooled reaction mixture is mixed with water and dichloromethane, the organic phase is separated off, dried over sodium sulfate, the solvent is removed in vacuo, the residue is taken up in 250 ml of acetonitrile, 0.4 g of palladium acetate are added and the mixture is heated for 24 hours Reflux temperature. The solvent is then distilled off and the residue is distilled under high vacuum. 18.3 g (75% of theory) of 2- (2-chloro-6-fluo ⁇ henyl) -4-chloromethyloxazole with a boiling point of 118-120 ° C. at 0.1 mbar are obtained.
- Emulsifier 1 part by weight of alkylaryl polyglycol ether
- active compound 1 part by weight of active compound is mixed with the stated amount of solvent and the stated amount of emulsifier, and the concentrate is diluted with water to the desired concentrations.
- Bean plants Phaseolus vulgaris
- which are heavily infested with all stages of development of the common spider mite (Tetranychus urticae) are immersed in an active ingredient preparation of the desired concentration.
- the kill is determined in percent. 100% means that all spider mites have been killed; 0% means that no spider mites have been killed.
- Emulsifier 1 part by weight of alkylaryl polyglycol ether To produce a suitable preparation of active compound, 1 part by weight of active compound is mixed with the stated amount of solvent and the stated amount of emulsifier, and the concentrate is diluted with water to the desired concentration.
- Cabbage leaves (Brassica oleracea) are treated by being dipped into the preparation of active compound of the desired concentration and populated with horseradish beetle larvae (Phaedon cochleariae) while the leaves are still moist.
- the kill is determined in percent. 100% means that all beetle larvae have been killed; 0% means that no beetle larvae have been killed. In this test, e.g. the compound of preparation example 1 at an exemplary concentration of 0.1% (percent by weight) kills 100%.
