摘要：
Compounds of Formula (1) and processes for their preparation, their N-oxides and agriculturally suitable salts, are disclosed which are useful for controlling undesired vegetation wherein Q, X1, X2, X3, R1, R2, R6 and R7 are as defined in the disclosure. Also disclosed are novel intermediates of Formula (5), Formula (8) and Formula (20) wherein R27 is —(CR6R7)q—Q; R6, R7, q, Q, X1 and X2 are as defined in the disclosure. Also disclosed are compositions containing the compounds of Formula (1) and a method for controlling undesired vegetation which involves contacting the vegetation or its environment with an effective amount of a compound of Formula (1).
