Definitions
- the present invention relates to a new process for the preparation of benzofurandione oxime derivatives.
- R 1 represents substituted or unsubstituted alkyl
- R 3 represents hydrogen, substituted or unsubstituted alkyl, alkoxy, haloalkoxy or halogen
- R 1 and R 3 have the meaning given above, and
- R 2 represents hydrogen, or substituted or unsubstituted alkyl
- dialkylsilyl chloride in the presence of dialkyl sulfoxide, optionally in a diluent and / or a solvent.
- Acids in the sense of the invention are more highly concentrated acids, in particular mineral acids.
- Preferred mineral acids are sulfuric acid, preferably 10 to 90% sulfuric acid, in particular semi-concentrated commercially available sulfuric acid, and / or phosphoric acid, preferably 20 to 95% phosphoric acid, in particular commercially available 85% phosphoric acid.
- Diluents and / or solvents by way of example and preferably water; Alcohols, especially methanol; Ether. especially dimethoxyethane, Tetrahydrofuran, methyl tert-butyl ether or tert-amyl methyl ether; Alkyl nitriles, especially acetonitrile; Ketones, in particular acetone or solvent mixtures thereof, in particular alcohol-water mixtures, are used.
- ethers in particular dimethoxyethane, tetrahydrofuran, methyl tert-butyl ether or tert-amyl methyl ether, are used as diluents and / or solvents; Alkyl nitriles, especially acetonitrile; N-methyl pyrrolidone; Alkane carboxylic acid esters, especially ethyl acetate; Ketones, especially acetone or solvent mixtures thereof are used.
- reaction of compounds of formula (II) with acids takes place in a temperature range from 0 ° C to 100 ° C, preferably in a temperature range from 20 ° C to 80 ° C.
- reaction of compounds of formula (II) with trialkylsilyl chloride in the presence of dialkyl sulfoxide takes place in a temperature range from 0 ° C. to the reflux temperature of the particular mixture, preferably at the reflux temperature.
- reaction of compounds of formula (II) is carried out under normal pressure, under elevated or under reduced pressure, preferably under normal pressure.
- the compounds of formula (II) are used as E / Z isomer mixtures or as pure isomers.
- the compounds of the formula (I) obtainable by the process according to the invention are then obtained in the form of the isomer mixtures or in the form of the pure isomers.
- the isomer mixtures obtained can optionally by customary methods, for. B. separated by chromatography into the pure isomers.
- the starting materials are defined by formula (II) above.
- the saturated or unsaturated hydrocarbon chains are each straight-chain or branched.
- alkyl represents C 1 -C 4 -alkyl, in particular methyl, ethyl, n-propyl, i-propyl, n-butyl, s-butyl, t-butyl or i-butyl.
- alkoxy is C r C 4 alkyl, in particular methoxy, ethoxy, n-propoxy, i-propoxy, n-butoxy, s-butoxy, t-butoxy or i-butoxy.
- Alkyloxycarbonyl or halogen preferred.
- Halogen generally represents fluorine, chlorine, bromine or iodine, preferably fluorine, chlorine or bromine, in particular fluorine or chlorine.
- R ' is preferably methyl.
- R 2 is preferably hydrogen or 2-hydroxyethyl, in particular hydrogen.
- R 3 is preferably hydrogen.
- A-19706399, DE-A-19706396 and EP-A-0 846 691 The compounds of formula (II) which are not yet known can be prepared by the processes described in DE-A-19706399, DE-A-19706396 and / or EP-A-0 846 691.
- a decisive advantage of the method according to the invention is the increased yield compared to the known methods.
- Another advantage of the process according to the invention is that the use of mixtures of isomers results in the majority of the E isomers. It is also extremely surprising to the person skilled in the art that the reaction of compounds of the formula (II) can be carried out in an acidic medium.
- the process is used for the production of important intermediates of formula (I) which facilitate the production of known pesticides.
- the reaction mixture is stirred at 55 ° C. for one hour and under reflux for one hour until the evolution of gas has ended.
- the mixture is then cooled to 20 ° C., the suspension is suctioned off and washed with acetonitrile.
- the orange filtrate is added dropwise to 18 l of ice water and 2 l of petroleum ether within 30 minutes.
- the suspension is stirred for 30 minutes at 20 ° C, the product settles in the upper petroleum ether phase.
- the lower aqueous phase is drained off and the product is suctioned off in the PE phase and washed with 1.5 l of petroleum ether, 4.0 l of water and 1.0 l of petroleum ether and dried in vacuo at 40.degree.
