<p>Herbicidal trans-2-[(3-chloroallyloxyimino)alkyl]-5-(substituted sulfinylalkyl)-cyclohexane-1,3-diones especially useful as selective herbicides active against grassy weeds are represented by the general formula: <CHEM> wherein R is lower alkyl; R<1> is hydrogen, a compatible cation, or the group - @R<6> in which R<6> is lower alkyl, phenyl, indenyl, naphthyl or benzyl; R<2> is hydrogen, carboxy, or lower alkoxycarbonyl; R<3> is lower alkylene; R<4> is lower alkyl, phenyl or substituted phenyl having 1 to 3 substituents independently selected from lower alkyl, lower alkoxy, halo and haloalkyl having 1 to 4 carbon atoms and 1 to 3 halo substituents independently selected from fluoro, chloro, bromo and iodo; R<5> is hydrogen or lower alkyl; and the designation @ indicates trans-orientation with respect to the double bond. The compounds can be prepared via oxidation of the corresponding 5-(substituted thioalkyl) precursors.</p> |
