Substituted triazolopyrimidines of the formula I n n n n n n n n n n in which the substituents are as defined below:n R 1 is alkyl, haloalkyl, cycloalkyl, halocycloalkyl, alkenyl, haloalkenyl, cycloalkenyl, halocycloalkenyl, alkynyl, haloalkynyl or phenyl, naphthyl, or a five- or six-membered saturated, partially unsaturated or aromatic heterocycle comprising one to four heteroatoms from the group consisting of O, N and S, R 2 is hydrogen or a group R 1 ,n R 1 and R 2 together with the nitrogen atom, to which they are attached, may also form a five- or six-membered heterocyclyl or heteroaryl which is attached via N and which may comprise one to three further heteroatoms from the groups consisting of O, N and S as ring member and/or may be substituted according to the description; n L is fluorine, chlorine or methyl; X is cyano, C 1 -C 4 -alkyl, C 1 -C 4 -alkoxy or C 1 -C 2 -haloalkoxy,n nwhere X is not methyl if R 1 and R 2 together are n-pentylene or 3-methyl-n-pentylene and L is fluorine, or R 1 and R 2 together are 3-methyl-n-pentylene and L is chlorine;n nprocesses and intermediates for preparing these compounds, compositions comprising them and their use for controlling phytopathogenic harmful fungi. |
