The present invention relates to novel compounds and mixtures of geometrical isomers, which are represented by the formula:
wherein
R1 and R2independently 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.
本发明涉及一类新的化合物及几何异构体的混合物,其由以下公式表示:其中R1和R2彼此独立地为C1-6烷基,C1-6卤代烷基,C3-8环烷基,C2-6烯基,C2-6卤代烯基,C3-6炔基或可选地被取代的苯基;或者R1和R2与它们所连接的氮原子一起形成一个可能被苯并环合的、5成员或6成员的杂环环,该环可能被卤素或C1-4烷基取代;R3是氢或C1-6烷基;R4是氢或C1-6烷基;或者R3和R4与它们所连接的碳原子一起形成环戊基亚基或环己基亚基;并且R5是C1-6烷基,C3-6烯基或苄基;进一步涉及到它们的制备过程和新中间体,以及它们作为除草剂的使用。
