Patent

CA 2210447

The present invention relates to novel compounds and mixtures of geometrical isomers, which are represented by the formula: Image (I) wherein R1 and R2 independently of one another are C1-6 alkyl, C1-6 haloalkyl, C3-8 cycloalkyl, C2-6 alkenyl, C2-6 haloalkenyl, C3-6 alkynyl or optionally substituted phenyl; or R1 and R2, together with the nitrogen atom to which they are bonded, form a 5-membered or 6-membered heterocyclic ring which may be benzo-fused or which may be substituted by halogen or C1-4 alkyl; R3 is hydrogen or C1-6 alkyl; R4 is hydrogen or C1-6 alkyl; or R3 and R4, together with the carbon atoms to which they are bonded, form cyclopentylidene or cyclohexylidene; and R5 is C1-6 alkyl, C3-6 alkenyl or benzyl; further to processes and new intermediates for their production and to their use as herbicides.

Nouveaux composés et mélanges d'isomères géométriques, de formule Image (I), où R1 et R2 sont chacun, indépendamment l'un de l'autre, un groupe alkyle C1-6, haloalkyle C1-6, cycloalkyle C3-8, alcényle C2-6, haloalcényle C2-6, alcynyle C3-6 ou phényle avec substitution facultative; ou R1 et R2 forment ensemble avec l'atome d'azote auquel ils sont liés un hétérocycle à 5 ou 6 chaînons, avec condensation benzo ou substitution par un halogène ou un groupe alkyle; R3 est un hydrogène ou un alkyle C1-6; R4 est un hydrogène ou un alkyle C1-6; ou R3 et R4 forment ensemble, avec les atomes de carbone auxquels ils sont liés, un cyclopentylidène ou un cyclohexylidène; R5 est un alkyle C1-6, alcényle C3-6 ou benzyle; procédés et nouveaux intermédiaires pour leur production et leur utilisation comme herbicides.
