摘要:
Disclosed are compounds of FormulaIandN-oxides or salts thereof,wherein R1is C1-C4alkyl or C3-C6cycloalkyl; R2is H, Cl, Br or I; R3is Cl or OR4; R4is H or C1-C4alkyl; R5is H, F, Cl or CH3; and R6is H or Cl; provided (a) when R3is OR4and R4and R5are both H, then R6is Cl; and (b) when R2is Br, R3is OR4and R4is H, then R6is H. Also disclosed is a composition containing a compound of FormulaI, and methods for controlling undesired vegetation comprising contacting the undesired vegetation or its environment with an effective amount of a compound of FormulaIor a composition thereof. Also dislosed are methods for preparing a compound of FormulaI.所揭示的是式I化合物及其N-氧化物或其鹽,其中R1係C1-C4烷基或C3-C6環烷基;R2係H、Cl、Br、或I;R3係Cl或OR4;R4係H或C1-C4烷基;R5係H、F、Cl、或CH3;且R6係H或Cl;前提是(a)當R3係OR4且R4及R5皆係H時,則R6係Cl;及(b)當R2係Br,R3係OR4且R4係H時,則R6係H。亦揭示的是一種含有式I化合物之組成物,以及用於防制非所欲植生之方法,該方法包含使該非所欲植生或其環境與有效量的式I化合物或其組成物接觸。亦揭示的是用於製備式I化合物之方法。
