Tyskland (DE) (74) Oy Koi ster Ab (54) Morpholine derivatives useful as fungicides -Sasom fungisider användbara morpholine derivatives The present invention relates to novel valuable morpholine derivatives and their salts and molecular and additive compounds having good fungicidal activity.

It is known that N-tridecyl-2,5-dimethylmorpholine and its salts and its molecular and addition compounds are used as fungicides (DE patents 11 64 152 and 11 73 722 and DE application 24 61 513).

It has been found that morpholine derivatives of the formula R1 R1 “3 / ΓΛ · Β3 Ά

r2r4 2 67379 12 3 4 wherein R, R, R and R represent hydrogen, methyl or ethyl, and their salts and molecular and addition compounds have a good fungicidal effect which is far superior to that of known morpholine derivatives.

Salts are, for example, salts with inorganic or organic acids, e.g. chlorides, fluorides, bromides, iodides, sulphates, nitrates, phosphates, acetates, propionates or fumarates, molecular or addition compounds are formed, for example, with surfactant acids, e.g. dodecylbenzene benzene.

In the case of 2,6-dimethyl derivatives, the new compounds can be isolated as cis and trans isomers. They are prepared, for example, by reacting 2,6-dimethylmorpholine with 3-p-tert-butylphenyl-2-methylpropanal in the presence of a diluent, e.g. formic acid, at temperatures of 50-110 ° C.

The following examples illustrate the preparation of the new compounds.

Example 1 Synthesis of N- (3-p-tert-butylphenyl-2-methyl-1-propyl) -cis-2,6-dimethylmorpholine 2,6-Dimethylmorpholine obtained by cyclization with sulfuric acid catalyzed by diisopropanolamine is separated into cis- and trans-forms by fractional distillation in a distillation column packed with stainless steel wire coils. About 75% (w / w) of 2,6-dimethylmorpholine is in the cis form, the rest in the trans form. Separation of the isomers by fractional distillation is accomplished in a column with about 40 separation bases. the cis form distills as a 99% product at 80-81 ° C at 100 torr. The trans form of 2,6-dimethylmorpholine can be obtained under the same conditions as more than 95% product at a distillation temperature of 88-89 ° at 100 torr.

575 g of 98% formic acid are first placed in a stirrer equipped with a reflux condenser, a thermometer and a dropping funnel. 345 g of 99% 2,6-cis-dimethylmorpholine are then added dropwise, with stirring and cooling. The mixture is then slowly heated to 70 ° C in a water bath. Within 4 hours, 612 g of 3-p-tert-butylphenyl-2-methylpropanal are added dropwise to the reaction mixture, maintaining the temperature at about 377379 at 100 ° C. During condensation, strong CO2 formation occurs. After completion of the reaction, the temperature of the mixture is maintained at 100 ° C for a further 2 hours with stirring.

The excess formic acid is then distilled off in vacuo. More complete separation of formic acid takes place in a water-vacuum at 100 ° C.

The base is liberated from the formate by dropwise addition of 500 g of a 40% aqueous sodium hydroxide solution. The addition of sodium hydroxide is conveniently carried out at 80-100 ° C in order to make the resulting amine phase more miscible with the lye phase. To reduce the viscosity, 200 g of toluene are added. After separation of the lye phase, the organic phase is washed twice with 250 g portions of water. For further purification, the amine is fractionally distilled under a 0.2 torr vacuum distillation column with 5 bottoms. In addition to a small pre-distillate (up to 143 ° C under a vacuum of 0.2 torr: 50 g), 865 g of N- (3-tert-butylphenyl-2-methyl-1-propyl) -2,6-cis-dimethylmorpholine are obtained. This distills under a vacuum of 0.2 torr at 143-146 ° C. Based on gas chromatographic analysis, the amine contains more than 98% pure substance. Calculated from the aldehyde, the yield was 84.5%.

For conversion to the hydrochloride, 30 g of pure product are dissolved in 50 g of ethanol saturated with hydrogen chloride at room temperature. After cooling, 23 g of hydrochloride melting at 220 ° C are obtained in very pure form.

Example 2 Synthesis of N- (3-p-tert-butylphenyl-2-methyl-1-propyl) -2,6-trans-dimethylmorpholine To 70 g of 98% formic acid is added under ice-cooling 29 g of 2,6-trans-formic acid. dimethylmorpholine. 41 g of 3-p-tert-butylphenyl-2-methylpropanal are then added with stirring. The reaction mixture is heated at 100 ° C for 6 hours. At the onset of the reaction, a very strong evolution of CC> 2 occurs, which after about an hour deteriorates considerably. Further processing takes place as described in more detail in Example 1.

N- (3-p-tert-butylphenyl-2-methyl-1-propyl) -2,6-trans-dimethylmorpholine distills under vacuum at 5 torr at 168-169 ° C.

They have a systemic effect; they are absorbed both through the roots and also through the leaves and migrate to the cellular tissue of plants.

The substances are used, for example, by wetting, spraying, dusting or covering plants or seeds with active ingredients.

When new active ingredients are used to treat plants against fungal infections, the application rates are between 0.025 and 5 kg of active ingredient per hectare of surface area. To protect the surface of trees and fruits, the active ingredients can also be used in connection with artificial dispersions, in the form of dispersions of 0.25 to 5% by weight of the dispersion. Fungicides generally contain from 0.1 to 95% by weight of active ingredient, mainly from 0.5 to 90%.
