The innovation relates to new 3-phenyl-4-cyanpyrol derivation with the general formula:<IMAGE>where X has one of the following meanings: a: hydrogen or CO-R1 group, where R1 is C1-C6 alkyl group, unsubstituted or substituted with halogen atom or C1-C6 alkoxy group; or also a C3-C6 alkenyl group, C3-C6 alkynyl group; or also C1-C6 alkoxy group; or also a C3-C6 alkenyl oxy group, C3-C6 cycloalkyl group, or tetrahydrofur-2-ilgroup. b: S-R2, where R2 is C1-C3 halogenoalkyl group; c: CH(Y)R3 where R3 is hydrogen or C1-C3 halogenoalkyl group, but Y is hydroxyl group, halogen atom or -OC(O)R4 where R4 is C1-C8 alkyl group; C1-C8 halogen-alkyl group, C2-C6 alkenyl group, tetrahydrofur-2-ilgroup, tetrahidropiran-2-ilgroup or C1-C6 alkoxy-carbonyl group, d: CH2-Z where Z is one of the groups<IMAGE>whereas in these formulas each of R5 and R6 independently from each other is a hydrogen, C1-C6 alkyl group that can be substituted or unsubstituted with cyan group or C1-C6 alkoxy-carbonyl group; or also there is a C3-C6 alkenyl group, C3-C6 alkynyl group, C3-C6 cycloalkynyl group; or also a phenyl group which is unsubstituted or substituted with halogen group, C1-C6 alkyl group, C1-C6 halogenoalkyl group and/or C1-C6 alkoxy group under a condition that only R5 and R6 can be hydrogen; each of R7 and R8 independently from each other a hydrogen, C1-C6 alkyl group. C1-C6 alkoxy-carbonyl group, or they both make a condensed redolent ring; each of R9-R10 independently from each other a hydrogen, C1-C6 alkyl group or C1-C6 alkoxy-carbonyl group, but X is oxygen or sulphur atom, >C=O group or >N-R11 group where R11 is hydrogen, C1-C6 alkyl group, formyl group, C1-C6 alkanoyl group or C1-C6 alkoxy-carbonyl group: n is 0 or 1. New substances are valid in fighting against harmful microorganisms, especially with phytopathogenic fungus. They along with corresponding additives can be used in form of compositions, and they are good for protection of cultivated plants from influence of harmful microorganisms. |
