FUNGICIDE COMPOSITION, DERIVATIVES OF TRIAZOLOPYRIMIDINE, METHOD OF THEIR SYNTHESIS AND METHOD OF FUNGI CONTROL Russian patent published in 1999 - IPC

FIELD: organic chemistry, fungicides. SUBSTANCE: invention relates to a fungicide composition, new derivatives of triazolopyrimidine, a method of their synthesis and a method of fungi control. Invention describes a fungicide composition containing an active component - a derivative of triazolopyrimidine. Composition has an effective amount of triazolopyrimidine compound as an indicated derivative of the general formula (I) where R means C₁-C₆-alkyl, C₁-C₆-alkoxy-group, C₃-C₈-cycloalkyl-group, phenyl substituted with 1-3 substituents taken from: halogen atoms, C₁-C₄-alkyl, C₁-C₄-halogenalkyl, C₁-C₄-alkoxy-, C₁-C₄-halogenalkoxy- -group, halogensulfonyl-group, phenyl, phenoxy- and benzylhydroxy-groups, C₁-C₄-alkoxy-, phenylhydroxy-group substituted with halogen atom or C₁-C₄-alkyl; naphthyl or thienyl; Hal - Cl or Br atom. Invention describes a method of synthesis of derivatives of triazolopyrimidine of the formula (I) that involves an interaction of compound of the general fomula (II) where value R is given in p. p. 5 and 6 of the invention claims with chlorinating or brominating agent. Method of struggle against fungi involves treatment with compound of the formula (I). EFFECT: improved method of synthesis, enhanced effectiveness of compounds. 10 cl, 6 tbl
