Abstract
The present invention provides pesticidally active compounds of the general formula I (I) in which R represents a group of the formula in which n represents 0, 1, 2 or 3 and each X represents an alkoxy group or a halogen atom; when n represents 2 or 3 the substituents represented by X may be the same or different.
Description
The present invention is concerned with methods of treating plants and crops with pesticidally active, especially insecticidally and ovicidally active, 2-propynylamine derivatives and with pesticidal preparations suitable therefor containing such 2-propynylamine derivatives.
& There have already become known as monoamine oxidase inhibitors, compounds which include for example, trans-2-phenylcyclopropylamine sulphate, l-isonicotinyl-2-isopropyl hydrazine phosphate, isonicotinic acid 2-{2-(benzylcarbamoyl)-ethyl}-hydrazide and also a 2-propynylamine derivative, namely N-benzyl-K-m2thyl-2-propynylamine.
It has now been found that 2-propynylamine derivatives of the general formula I
CH3
R-CHj-N-CH2-C=CH (I), in which R represents an unsubstituted or substituted aromatic hydrocarbon group, and salts thereof, surprisingly exhibit an outstanding action against insect pests as well as against their eggs.
This action is especially.surprising and could not have been foreseen, since the other oxidase inhibitors mentioned above do not have such an action.
The action found is effective in particular, agains Lepidoptera, thus, for example, against Spodoptera littoratis (Egyptian cotton moth),
Namestra brassicae (cabbage moth) and Pieris brassicae (large cabbage butterfly).
Moreover, the compounds of the general formula I and their salts are distinguished by a slight toxicity towards warm-blooded animals.
Thus, for example, the acute LDS0-mouse per os is 700 mg/kg in the case
- 2 45599 of N-benzyl-N-methyl-2-propynylamine, and 305 mg/kg in the case of N(2-chloro-benzyl)-N-methyl-2-propynylami ne.
Furthermore, as these compounds are particularly well tolerated by plants, they can be used advantageously and without danger against pests in vegetable crops.
As such crops there may be mentioned, for example, crops of cotton, tomatoes, cauliflower, cabbage, dwarf beans. Riff beans, sugar beet, maize and rice.
The present invention accordingly provides a pesticidal preparation, which comprises at least one compound selected from compounds of the general formula I
CH,
I
R-—CH^ N CH2—CeCH (I), in which R represents an unsubstituted or substituted aromatic hydrocarbon group, and salts thereof, in admixture or conjunction with a suitable carrier.
The present invention further provides a pesticidal preparation which comprises at least two compounds selected from compounds of the general formula I, in which R has the meaning given above, and salts thereof.
The present invention further provides a method of protecting a living plant against pests, wherein the plant is treated with at least one compound selected from compounds of the general formula I, in which
- 3 R has the meaning given above, and salts thereof.
The present invention further provides a method of protecting a crop against pests, wherein the crop is treated with at least one compound selected from compounds of the general formula I, in v’Ah R h s the meaning given above, and salts thereof.
The most favourable application concentration for the active compounds used in accordance with the methods of the present invention when applied in the form of pesticidal preparations is approximately 0.01% to 1.0%, preferably 0.05% to 0.2%, by weight; when two or more of these active compounds are used these concentration ranges refer of course to the total concentrations.
Among the compounds of the general formula I and their salts there may be used in accordance with the present invention more especially those in which R represents a group of the formula
in which £ represents 0, 1, 2 or 3 and each X represents an alkyl, alkoxy or nitro group or a halogen atom; when n, represents 2 or 3 the substituents represented by X may be the same or different.
However, optimum actions occur in the case of those compounds in 20 which according to the general formula I, £ represents 0, 1, 2 or 3 and X represents an alkyl or alkoxy group containing 1 to 3 carbon atoms, a chlorine atom or a nitro group.
- 4 45599
The compounds of the general formula I used in accordance with the present invention may be applied in each case, in the free form or in the form of salts thereof with inorganic or organic acids.
Among the salts, the hydrochlorides are especially suitable for 5 use in accordance with the present invention.
Specific compounds and salts which may be used in accordance with the present invention are, for example, those listed in the following Table:

The free bases are colourless liquids that are readily soluble in organic solvents, for exiample hydrocarbons, halogenated hydrocarbons, ethers, ketones, alcohols, esters, carboxylic acid amides and carboxylic acid nitriles. Their solubility in water is slight. The 2-propynylamine derivatives can be isolated easily as crystalline bodies in the form of their hydrogen halide salts; the latter are readily soluble in water, but only sparingly soluble in organic solvents.
The compounds used in accordance with the present invention are known per se or may be prepared by processess known per se.
They may be prepared, for example, by reacting a propargyl halide of the general formula
HC=C—CH2—Hal, in which Hal represents a halogen atom, preferably a chlorine or bromine atom, in the presence of a solvent and of an acid-binding agent with an N-substituted methylamine of the general formula
R—CHj—NH—CH3, in which R has the meaning given above, and, if desired, converting the resulting compound of the general formula I into a salt thereof with
- 6 45399 an acid.
In order to synthesize the compounds of the general formula I, the reactants are used in approximately equimolar quantities. Suitable reaction media are solvents that are inert towards the reactants. The following are mentioned as examples of such solvents: halogenated hydrocarbons, for example methylene chloride, chloroform and carbon tetrachloride, aliphatic and aromatic hydrocarbons, for example petroleum ether, cyclohexane, benzene, toluene and xylene, alcohols for example methanol and ethanol, and ketones, for example acetone, methyl isobutyl ketone and isophorone.
The reaction takes place between 0° and 100°C, but generally between room temperature and the reflux temperature of the reaction mixture in question.
Tertiary amines, for example triethylamine or Ν,Ν-dimethylaniline, pyridine bases or suitable inorganic bases, for example oxides, hydroxides and carbonates of alkali metals and alkaline earth metals, are used to bind the hydrohalic acids formed.
As a rule, the propargyl halide is added portionwise to the appropriate N-substituted methylamine and the hydrogen halide acceptor, but it is also possible to add the reactants in the reverse order.
After the reaction has taken place, the hydrogen halide salt formed is removed by filtration and washed with the appropriate solvent. After removing the solvent from the filtrate, the residue is subjected to fractional distillation under reduced pressure and the reaction products are obtained as colourless liquids.
The salts of the 2-propynylamine derivatives may, if desired, be
- 7 Ρ 45599 obtained by treating the amines with, for example, ethereal solutions of the acids while cooling.
They can be easily recrystallized from a suitable organic solvent, for example a mixture of ethanol and ether.
The active compounds used in accordance with the present invention may be applied alone, or in the form of mixtures with one another or with other active substances. If desired, other plant-protecting agents or pest-combating agents may be added depending on the purpose desired.
The action and speed of action can be enhanced, for example, by action-increasing additives, for example organic solvents, wetting agents and oils) This permits a reduction in the quantity of the active substance itself applied.
The active compounds used in accordance with the present invention or mixtures thereof are advantageously applied in the form of pesticidal preparations, for example powders, strewable preparations, granules, solutions, emulsions or suspensions, with the addition of liquid and/or solid vehicles or diluents and, if desired, of surface-active agents, for example wetting, adherent, emulsifying and/or dispersing agents.
Suitable liquid carriers are, for example, water, aliphatic hydrocarbons, aromatic hydrocarbons, for example benzene, toluene and xylene, cyclohexanone, isophorone, dimethyl sulphoxide and dimethylformamide, and also mineral oil fractions.
Suitable solid carriers are, for example, mineral earths, for example Tonsil (Trade Mark), silica gel, talcum, kaolin, attaclay, limestone and silicic acid, and vegetable products, for example meals.

As surface-active agents there may be mentioned, for example, calcium lignin sulphonate, polyoxyethylene alkyl phenyl ethers, naphthalene sulphonic acids and salts thereof, phenol sulphonic acids and salts thereof, formaldehyde condensates, fatty alcohol sulphates and also substituted benzene sulphonic acids and salts thereof.
The total amount of the active substance or substances in the various pesticidal preparations may vary within wide limits. For example, concentrate preparations ready for dilution before application may contain approximately 10 to 80% by weight of active substance(s), approximately 90 to 20% by weight of liquid or solid carrier and, if desired, also up to 20% by weight of surface-active agent(s).
The active compounds may be applied in the usual manner, for example with water as carrier in quantities of spray liquor of about 100 to 1000 litres per hectare. It is also possible to apply the active compounds by the so-called low-volume and ultra-low-volume methods as well as in the form of so-called microgranules.
The production of these preparations may be carried out in a manner known per se, for example by mixing or grinding methods. If desired, the individual components may be mixed together only shortly before they are used, as is the case in practice, for example, in the so-called tank-mix method.
The following Examples illustrate the invention. Examples 1 and 2 illustrate the manufacture of the compounds of the general formula I and their salts, and Examples 3 to 5 illustrate their pesticidal action.
