- the amount of active ingredient used can vary over a wide range. It essentially depends on the type of effect desired. In general, the application rates are between 1 g and 10 kg of active ingredient per hectare of soil, preferably between 5 g and 5 kg per ha.
- the stereochem. Information in the right column relates to the carbon atom connected to R 4 .
- Example (IT1) for example the compounds of the general formula (II) listed in Table 2 below can also be prepared.
- a mixture of 160 g (1.25 mol) racem. 1- (Thien-2-yl) ethylamine, 140 g methyl methoxyacetate and 1000 ml methyl t-butyl ether is stirred at room temperature (approx. 20 ° C.) with 15 g Novozym 435 ® (immobilized lipase from Candida antarctica, 7300 U / g).
- the mixture is stirred at 60 ° C for 24 hours; then another 5 g of Novozym 435 are added and the mixture is stirred at 60 ° C. for a further 24 hours.
- the enzyme is then separated off by filtration, the filtrate is concentrated in a water jet vacuum, the residue in
- the organic phase - which contains the (R) -N-methoxyacetyl-l- (thien-2-yl) ethylamine - is then separated off and worked up separately.
- the aqueous phase is made alkaline with 2N sodium hydroxide solution and shaken with methylene chloride.
- the resulting organic phase is then separated off, dried with sodium sulfate and filtered.
- the filtrate is concentrated in a water jet vacuum and the residue is worked up by distillation under reduced pressure. 35.5 g (22% of theory) of (S) -l- (thien-2-yl) ethylamine with a boiling point of 50 ° C. (at 0.8 mbar) are obtained.
- step 1 - which contains the (R) -N-methoxyacetyl-l- (thien-2-yl) ethylamine - is dried with sodium sulfate and filtered. The solvent is carefully distilled off from the filtrate under reduced pressure.
- 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, the stated amount of emulsifier is added and the concentrate is diluted with water to the desired concentration.
- Seeds of the test plants are sown in normal soil. After 24 hours, the soil is sprayed with the active ingredient preparation in such a way that the desired amount of active ingredient is applied per unit area.
- the concentration of active ingredient in the spray liquor is chosen so that the desired amount of active ingredient is applied in 1000 liters of water per hectare.
- Emulsifier 1 part by weight of alkylaryl polyglycol ether
- Test plants which have a height of 5-15 cm are sprayed with the active compound preparation in such a way that the desired amounts of active compound are applied per unit area.
- the concentration of the spray liquor is chosen so that in
- the degree of damage to the plants is rated in% damage compared to the development of the untreated control.
