DERIVATIVES OF BENZAMIDE OXIME, METHOD OF THEIR SYNTHESIS AND FUNGICIDE AGENT FOR PROTECTION OF AGRICULTURE PLANTS Russian patent published in 1999 - IPC

FIELD: organic chemistry, fungicides, agriculture. SUBSTANCE: invention relates to derivatives of benzamide oxime of the formula (I) where R¹ means unsubstituted or substituted C₁-C₄-alkyl, unsubstituted or substituted C₂-C₄-alkenyl or unsubstituted or substituted C₂-C₄-alkynyl; R² means phenyl optionally having substituents taken among the group including halogen atom, C₁-C₃-alkyl, C₁-C₃-alkoxy-group, C₂-C₄-alkenyloxy-group, C₁-C₃-halogenalkyl and C₁-C₃-halogenalkoxy-group or 5-membered aromatic heterocycle containing nitrogen or sulfur atoms as heteroatoms and optionally substituted with C₁-C₃-alkyl; X¹ means C₁-C₄-halogenalkyl; X²,X³,X⁴,X⁵ mean independently hydrogen atom, halohalogen, C₁-C₄-alkyl, C₁-C₄-halogenalkyl, C₁-C₄-alkoxy-group, C₁-C₄-alkylthio-group, C₁-C₄-alkylsulfonyl-group, C₁-C₄-alkylsulfinyl-group, nitro-group; r¹ and r² each means independently hydrogen atom, C₁-C₄-alkyl, C₁-C₄-alkoxy-group, C₁-C₄-alkylthio-group or r¹ and r² in common can form carbonyl. Compounds show the excellent fungicide activity and can be used in agriculture and gardening. Invention proposes also a method of synthesis of derivatives of benzamide oxime of the formula (I) by interaction of the compound of the formula (II) with the compound of the formula (III) and a fungicide agent for protection of agriculture plants. EFFECT: improved method of synthesis, enhanced fungicide activity of compounds. 4 cl, 5 tbl, 13 ex
