FUNGICIDAL TRIAZOLOPYRIMIDINES, METHOD FOR THE PRODUCTION THEREOF, USE THEREOF FOR CONTROLLING HARMFUL FUNGI, AND AGENTS CONTAINING SAID FUNGICIDAL TRIAZOLOPYRIMIDINES

摘要

Triazolopyrimidines of the formula I where the index and the substituents are as defined below: R¹ is C₁-C₁₀-alkyl, C₂-C₁₀-alkenyl, C₂-C₁₀-alkynyl, C₃-C₁₀-cycloalkyl, C₃-C₁₀-cycloalkenyl, phenyl, naphthyl, or a five- to ten-membered saturated, partially unsaturated or aromatic heterocycle which is attached via carbon to the triazolopyrimidine and contains one to four heteroatoms from the group consisting of N, O and S; R² is C₁-C₄-alkyl which may be substituted by halogen, cyano, nitro or C₁-C₂-alkoxy; n is 0 or an integer from 1 to 4; R is as defined in the description; X is SO_m-R^x, NR^xR^y or NR^x-(C-O)-R^y; m is 0 or an integer from 1 to 3; and processes for preparing these compounds, compositions comprising them and their use for controlling harmful fungi are described.
