Die in den vorstehend genannten Schriften beschriebenen Verbindungen sind als Pflanzenschutzmittel gegen Schadpilze geeignet.The compounds described in the abovementioned documents are suitable as crop protection agents against harmful fungi.
Ihre Wirkung ist jedoch in vielen Fällen nicht zufriedenstellend. Daher lag als Aufgabe zugrunde, Verbindungen mit verbesserter Wirksamkeit zu finden.However, their effect is unsatisfactory in many cases. Therefore, the task was to find compounds with improved effectiveness.
Demgemäß wurden die eingangs definierten Phenylpyrimidinderivate I gefunden. Außerdem wurden Verfahren zu ihrer Herstellung sowie sie enthaltende Mittel zur Bekämpfung von Schadpilzen und ihre Verwendung in diesem Sinne gefunden.Accordingly, the phenylpyrimidine derivatives I defined at the outset were found. In addition, processes for their preparation and agents containing them for controlling harmful fungi and their use in this sense have been found.
Die Verbindungen der Formel I weisen eine gegenüber den bekannten Verbindungen erhöhte Wirksamkeit gegen Schadpilze auf.The compounds of the formula I have an increased activity against harmful fungi compared to the known compounds.
Die Verbindungen I können auf verschiedenen Wegen erhalten werden.The compounds I can be obtained in various ways.
Vorteilhaft geht man zur Herstellung der Verbindungen der Formel I, in der R4 für Cyanooder eine über ein Heteroatom gebundene Gruppe steht, von Sulfonen der Formel II aus. In Formel II haben die Substituenten Xm und R1 bis R3 die Bedeutung wie in Formel I und R steht für Cι-C4-Alkyl, bevorzugt für Methyl.The preparation of the compounds of the formula I in which R 4 is cyano or a group bonded via a heteroatom is advantageously started from sulfones of the formula II. In formula II, the substituents X m and R 1 to R 3 have the meaning as in formula I and R represents -C 4 alkyl, preferably methyl.
Die Sulfone der Formel II werden mit Verbindungen der Formel III unter basischen Bedingungen umgesetzt. Aus praktischen Gründen kann alternativ direkt das Alkalimetall-, Erdalkalimetall- oder Ammoniumsalz der Verbindung III eingesetzt werden. The sulfones of formula II are reacted with compounds of formula III under basic conditions. Alternatively, for practical reasons, the alkali metal, alkaline earth metal or ammonium salt of compound III can be used directly.

DE-A 39 01 084; Chimia, Bd. 50, S. 525-530 (1996); Khi . Geterotsikl. Soedin, Bd. 12, S. 1696-1697 (1998)].This reaction usually takes place at temperatures from 25 ° C. to 250 ° C., preferably 40 ° C. to 210 ° C., in an inert organic solvent in the presence of a base [cf. DE-A 39 01 084; Chimia, Vol. 50, pp. 525-530 (1996); Khi. Geterotsikl. Soedin, Vol. 12, pp. 1696-1697 (1998)].
