摘要：
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.
