Abstract
Substituted aryl ether derived compounds represented by the general structure (I) are described. X and Y are independent of each other and are represented by hydrogen, halogen, cyano, nitro, (C1-4)alkyl, (C1-4)haloalkyl, or (C1-4)haloalkoxy; Z is oxygen or sulfur; Q is selected form Q1 to Q6; A is oxygen, sulfur, or imino; R1 is hydrogen, (C1-4)alkyl, (C1-4)haloalkyl, or amino and can be independent of each other in a single molecule; R2 and R3 are independent of each other and may be selected from the group consisting of hydrogen, halogen, cyano, nitro, (C1-4)alkyl, (C1-4)haloalkyl, (C2-6)alkenyl, (C2-6)haloalkenyl and amino which may be optionally substituted with (C1-4)alkyl or (C1-4)haloalkyl; Ar is substituted or unsubstituted carbocyclic or heterocyclic aromatic ring being at least a five or six membered ring. This ring can be fused with another substituted or unsubstituted five or six membered carbocyclic or heterocyclic ring. When Q is Q5, unsubstituted or substituted phenyl is excluded. Also described are the processes for the manufacture of these compounds and agriculturally suitable compositions containing these as active ingredients which are useful as herbicides for ge…
