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, X<1>, X<2>, X<3>, R<1>, R<2>, R<6> and R<7> are as defined in the disclosure. Also disclosed are novel intermediates of Formula (5), Formula (8) and Formula (20) wherein R<27> is -(CR<6>R<7>)q-Q; R<6>, R<7>, q, Q, X<1> and X<2> 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). |
