Description
  • [0001]
    The invention relates to novel halogenopyrimidines, to two processes for their preparation and to their use as pesticides.
  • [0002]
    Certain pyrimidines with a similar substitution pattern and their fungicidal action are already known (GB-A 2253624). However, the activity of these prior art compounds, in particular at low application rates and concentrations, is not entirely satisfactory in all areas of use.
  • [0003]
    This invention, accordingly, provides the novel halogenopyrimidines of the general formula (I)
  • [0004]
    in which
  • [0005]
    Z represents respectively optionally substituted cycloalkyl, aryl or heterocyclyl,
  • [0006]
    R represents hydrogen or alkyl,
  • [0007]
    Q represents oxygen or sulphur and
  • [0008]
    X represents halogen,
  • [0009]
    L1, L2, L3 and L4 are identical or different and, independently of one another, each represents hydrogen, halogen, cyano, nitro, respectively optionally halogen-substituted alkyl, alkoxy, alkylthio, alkylsulphinyl or alkylsulphonyl.
  • [0010]
    In the definitions, the saturated or unsaturated hydrocarbon chains, such as alkyl, alkanediyl, alkenyl or alkinyl, are in each case straight-chain or branched, including in combinations with hetero atoms, such as, for example, in alkoxy, alkylthio or alkylamino.
  • [0011]
    Aryl represents aromatic mono- or polycyclic hydrocarbon rings, such as, for example, phenyl, naphthyl, anthranyl, phenanthryl, preferably phenyl or naphthyl, in particular phenyl.
  • [0012]
    Heterocyclyl represents saturated or unsaturated, and aromatic, ring-shaped compounds in which at least one ring member is a hetero atom, i.e. an atom other than carbon. If the ring contains more than one hetero atom, these may be identical or different. Preferred hetero atoms are oxygen, nitrogen or sulphur. Optionally, the ring-shaped compounds may form a polycyclic ring system together with other carbocyclic or heterocyclic fused or bridged rings. Preference is given to mono- or bicyclic ring systems, in particular to mono- or bicyclic aromatic ring systems.
  • [0013]
    Cycloalkyl represents saturated carbocyclic compounds in the form of a ring which may form a polycyclic ring system together with other carbocyclic fused or bridged rings.
  • [0014]
    Furthermore, it has been found that the novel halogenopyrimidines of the general formula (I) are obtained when
  • [0015]
    a) 2-(2-hydroxy-phenyl)-2-methoxyimino-acetamides of the formula (II)
  • [0016]
    in which
  • [0017]
    R, L1, L2, L4 and L4 are each as defined above are reacted with a substituted halogenopyrimidine of the general formula (III)
  • [0018]
    in which
  • [0019]
    Z, Q and X are each as defined above and
  • [0020]
    Y1 represents halogen,
  • [0021]
    if appropriate in the presence of a diluent, if appropriate in the presence of an acid acceptor and if appropriate in the presence of a catalyst, or
  • [0022]
    b) phenoxypyrimidines of the general formula (IV)
  • [0023]
    in which
  • [0024]
    R, X, L1, L2, L3 and L4 are each as defined above and
  • [0025]
    Y2 represents halogen
  • [0026]
    are reacted with a ring compound of the general formula (V)
  • Z—Q—H  (V)
  • [0027]
    in which
  • [0028]
    Z and Q are each as defined above,
  • [0029]
    if appropriate in the presence of a diluent, if appropriate in the presence of an acid acceptor and if appropriate in the presence of a catalyst.
  • [0030]
    Finally, it has been found that the novel halogenopyrimidines of the general formula (I) have very strong fungicidal activity.
  • [0031]
    The compounds according to the invention may be present as mixtures of various possible isomeric forms, in particular of stereoisomers such as, for exmple, E- and Z-isomers. Both the E- and the Z-isomers and any mixtures of these isomers are claimed.

  • [0140]
    Depending on their particular physical and/or chemical properties, the active compounds can be converted to the customary formulations, such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols and microencapsulations in polymeric substances and in coating compositions for seeds, and ULV cool and warm fogging formulations.
  • [0141]
    These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is, liquid solvents, liquefied gases under pressure, and/or solid carriers, optionally with the use of surfactants, that is emulsifiers and/or dispersants, and/or foam formers. In the case of the use of water as an extender, organic solvents can, for example, also be used as auxiliary solvents. Essentially, the following are suitable as liquid solvents: aromatics such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics or chlorinated aliphatic hydrocarbons such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example petroleum fractions, alcohols such as butanol or glycol and their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents such as dimethylformamide or dimethyl sulphoxide, or else water. Liquefied gaseous extenders or carriers are to be understood as meaning liquids which are gaseous at standard temperature and under atmospheric pressure, for example aerosol propellants such as halogenated hydrocarbons, or else butane, propane, nitrogen and carbon dioxide. Suitable solid carriers are: for example ground natural minerals such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals such as highly disperse silica, alumina and silicates. Suitable solid carriers for granules are: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, or else synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks. Suitable emulsifiers and/or foam formers are: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates, or else protein hydrolysates. Suitable dispersants are: for example lignin-sulphite waste liquors and methylcellulose.
  • [0142]
    Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, or else natural phospholipids such as cephalins and lecithins and synthetic phospholipids can be used in the formulations. Other additives can be mineral and vegetable oils.
  • [0143]
    It is possible to use colourants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.
  • [0144]
    The formulations generally comprise between 0.1 and 95 per cent by weight of active compound, preferably between 0.5 and 90%.
  • [0145]
    The active compounds according to the invention can be used as such or in their formulations also mixed with known fungicides, bactericides, acaricides, nematicides or insecticides in order thus, for example, to widen the spectrum of action or to prevent development of resistance. In many cases, synergistic effects are achieved, i.e. the activity of the mixture exceeds the activity of the individual components.
