FIELD: chemistry. ^ SUBSTANCE: bonds are described for the formula (I) , where Y denotes oxygen, C(=CR6aR6b) or C1-C4alkyl group, which can contain one or two substitutes for R6; A1 denotes CR7; A2 denotes CR8; R1, R2, R7 and R8 which independently of each other denote hydrogen, C1-C6alkyl, a halogen; R6 denotes C1-C6alkoxycarbonyl; or 2 substitutes of R6 with one carbon atom form together a C2-C5alkyl chain; R3 denotes a hydroxyl group; Q denotes a radical , where p1 equals 0; m1 equals 1; X1 denotes C1-C6halogenalkyl; Z1 denotes C2-C6alkyl group, in which oxygen is included, and which can be substituted with the help of one L1; or Z1 denotes C1-C6alkyl; L1 denotes C1-C6alkoxy-group; R6a denotes C1-C6alkyl; R6b denotes C1C6alkyl; or argronomically accepted salt/tautomer of this bond. Also described are the bonds of the formulas (Da) , (Db) and (VII) , which are the initial and intermediate substances for getting the bonds of the formula (I). ^ EFFECT: bonds of the formula (I) possess herbicidal properties. ^
