TETRAZOLINONES

摘要

The present invention relates to novel compounds and mixtures of geometrical isomers, which are represented by the formula: <IMG> (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.
