Definitions
- the invention relates to new metal salt complexes of 1-phenyl-2-triazolyl-ethyl derivatives, a process for their preparation and their use as fungicides.
- the metal complexes of 1-phenyl-2-triazolyl-ethyl derivatives according to the invention show a considerably higher fungicidal activity, in particular against rust and mildew types, than the 1- [ß-aryl-ß (R-oxy ) -ethyl] -imidazoles and -triazoles, for example 1- [ß-butoxy-ß- (4'-chlorophenyl) -ethyl] -imidazole, which are chemically and effectively obvious substances, and as the zinc-ethylene-1,2 -bis-dithio- carbamidate, which is a known substance with the same direction of action.
- the active ingredients according to the invention thus represent an enrichment of technology.
- reaction sequence can be represented by the following formula:
- Formula 1 generally defines the 1-phenyl-2-triazolyl-ethyl derivatives to be used as starting materials.
- the procedure is expediently started from a 1-hydroxy-1-phenyl-2-triazolylethane derivative, the latter in a suitable inert solvent using alkali metal hydride or alkali metal amide in the alkali metal alcoholate of the formula IV transferred, and the latter is reacted immediately without isolation with a halide of the formula V, the compounds of the formula 11 being obtained in one operation with the emergence of alkali halide.
- the preparation of the alkanolates of the formula IV and the reaction with the halide of the formula V are expediently carried out in a two-phase system, for example aqueous sodium hydroxide solution or potassium hydroxide solution / toluene or methylene chloride, with the addition of a phase transfer catalyst, for example Ammonium or phosphonium compounds performed.
- a phase transfer catalyst for example Ammonium or phosphonium compounds performed.
- the 1-hydroxy-1-phenyl-2-triazolyl-ethane derivatives on which the alkanolates of the formula IV are based are known (cf. DT-OS 2431407 and DT-OS 2547953).
- the 1-halogen-1-phenyl-2-triazolyl-ethane derivatives of the formula VI are also known (cf. DT-OS 2547954).
- Examples of the 1-phenyl-2-triazolyl-ethyl derivatives of the formula 11 to be used as starting materials according to the invention are the following compounds in Tables 1, 2 and 3:

- the stoichiometric amount (depending on the oxidation state of the metal) of the compound of the formula 11 is employed per mol of the metal salt 111. These ratios can be exceeded by up to 20 mol% without significant reduction in yield.
- Working up is carried out in a manner which is customary and generally known for organic compounds, e.g. by suctioning off the precipitated complex and cleaning by recrystallization, e.g. from alcohol.
- the active substances according to the invention have a strong fungitoxic effect. They do not damage crops in the concentrations necessary to control fungi. For these reasons, they are suitable for use as crop protection agents for combating fungi. Fungitoxic agents in crop protection are used to control Plasmodiophoromycetes, Oomycetes, Chytridiomycetes, Zygomycetes, Ascomycetes, Basidiomycetes, Deuteromycetes.

- Venturia species such as against the apple scab pathogen (Fusicladium dendriticum)
- powdery mildew fungi for example for combating powdery mildew (Podosphaera leucotricha) and powdery mildew, and for other cereal diseases.
- the active compounds according to the invention can be used as crop protection agents for treating seeds or soil and for treating above-ground parts of plants.

These are made in a known manner, e.g. by mixing the active ingredients with extenders, that is to say liquid solvents, pressurized liquefied gases and / or solid carriers, if appropriate using surface-active agents, that is to say emulsifiers and / or dispersants and / or foam-generating agents. If water is used as an extender, e.g. organic solvents can also be used as auxiliary solvents.

- Aerosol propellants such as dichlorodifluoromethane or trichlorofluoromethane; as solid carriers: natural rock flour, such as kaolin, clay, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth and synthetic rock powder, such as highly disperse silica, aluminum oxide and silicates; as an emulsifier; nonionic and anionic emulsifiers such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, e.g.

- active compounds such as fungicides, insecticides, acaricides, nematicides, herbicides, bird repellants, growth agents, plant nutrients and agents which improve soil structure.
- the formulations generally contain between 0.1 and 95% by weight of active compound, preferably between 0.5 and 90%.
- the active compounds can be used as such, in the form of their formulations or in the use forms prepared therefrom by further dilution, such as ready-to-use solutions, emulsions, suspensions, powders, pastes and granules. They are used in the usual way, e.g. by pouring, spraying, spraying, dusting, scattering, dry pickling, wet pickling, wet pickling, slurry pickling or incrusting.
