FIELD: organic chemistry, herbicides.

SUBSTANCE: invention describes novel derivatives of the formula (I): wherein R¹ are similar or different and mean hydrogen atom (H),-CN, (C₁-C₈)-alkyl, (C₁-C₈)-alkoxy-group; A means phenyl, pyrazolyl wherein each of them is bound to X through carbon atom and substituted with one or two radicals comprising (C₁-C₈)-alkyl, (C₁-C₈)-halogenalkyl; X means oxygen atom (O); R² and R³ mean H; m means O; R⁶ means H, (C₁-C₈)-alkyl, (C₁-C₈)-alkylsulfonyl substituted with halogen atom; B means [(C₁-C₈)-alkyl]-carbonyl, [(C₃-C₆)-cycloalkyl]-carbonyl wherein each radical is not substituted or substituted with one or some radicals chosen from a row comprising halogen atom, (C₁-C₈)-alkoxy-group and [(C₁-C₈)-alkoxy]-carbonyl, (C₁-C₈)-alkylsulfonyl substituted with halogen atom, [(C₂-C₈)-alkenyl]-carbonyl, phenylcarbonyl substituted with one some radicals chosen from a row comprising halogen atom, (C₁-C₈)-alkyl and -NO₂, or di-[(C₁-C₈)-alkyl]-aminosulfonyl, formyl or group of the formula -CO-CO-R¹ wherein R¹ means (C₁-C₈)-alkyl or phenyl-substituted [(C₂-C₈)-alkenyl]-carbonyl, furancarbonyl, thienylcarbonyl, halogen-substituted phenylaminocarbonyl, dimethylaminosulfonyl or group of the formula: or wherein W means oxygen or sulfur atom; T means O; R¹¹ means unsubstituted (C₁-C₈)-alkyl or substituted with halogen atom; R¹² and R¹³ are similar or different and mean H, unsubstituted (C₁-C₈)-alkyl, with exception for N-hydroxy-N-[(6-phenoxy-2-pyridyl)methyl]-acetamide, and a herbicide agent comprising compound of the formula (I) and accessory substances used usually in preparing agents for plants protection. Proposed compounds possess the herbicide activity and therefore they can be used agriculture.

EFFECT: valuable properties of compounds and agents.
