Abstract: Novel herbicidal and defoliant substituted aniline derived compounds represented by general structure (I) are described. W, X, Y, Z, and Q are as defined in the disclosure. 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 general or selective pre-emergent or post-emergent control of undesired plant species and defoliants at very low concentrations of these biologically active compounds.

Abstract: Diaryl ether compounds useful in the control of weeds are described. An exemplary compound is represented by the general formula (I):
In this formula Q is represented by Q1
X and Y represent a hydrogen atom, halogen atom, cyano group, nitro group or (C1-6)haloalkyl group; R1 is halogen; R2 and R3 represent a hydrogen atom, a (C1-6)alkyl group or a (C1-6)haloalkyl group . Methods of making the compounds are also described.

Abstract: Diaryl ether compounds useful in the control of weeds are described. An exemplary compound is represented by the general formula (I):
In this formula Q is represented by Q9:
X and Y represent a hydrogen atom, halogen atom, cyano group, nitro group or (C1-6)haloalkyl group. A1 and A2 are independently oxygen or sulfur atoms. R9 and R10 represent a hydrogen atom, a (C1-6)alkyl group, an acyl group, or a (C1-6)alkylsulfonyl group; or R9 and R10 may form a ring consisting of polymethylene, (CH2)m groups, where m is an integer of 2, 3, 4 or 5, together with the nitrogen atom of NR9R10, which may or may not have a (C1-6)alkyl substituent. Methods of making the compounds are also described.
