Cyclohexenonoximethers, process and intermediates for their preparation and their use as herbicides.

cyclohexenone(R1 = Alkyl;A = optionally substituted alkylene or alkenylene,Z = a 5- or 6-membered heteroaromatic;X = optionally substituted amino, nitro, cyano, halogen, alkyl, Cl-C4-alkoxy, C4Alkylthio, C1-C4Haloalkyl, C1-C4-haloalkoxy, Carboxyl, C1-C4Alkoxycarbonyl, optionally substituted benzyloxycarbonyl, and phenyl;n = 0-3, or 1-4 for the case that Z is a halogen-substituted pyridyl;R2 = Alkoxyalkyl or alkylthioalkyl; optionally substituted cycloalkyl or cycloalkenyl; optionally substituted 5-membered saturated heterocycle containing one or two hetero atoms; optionally substituted 6- or 7-membered saturated or mono- or diunsaturated heterocycle with one or two Heteroatoamen; optionally substituted 5-membered heteroaromatic containing one to three heteroatoms; optionally substituted phenyl or pyridyl) and their agriculturally useful salts and esters of Ci-Cio-carboxylic acids and inorganic acids. The compounds I are suitable as herbicides.
