Compounds of the general formula (2) and isomeric and/or tautomeric forms thereof, characterized in that R<1> is hydrogen, optionally substituted alkyl, alkenyl, alkynyl, optionally substituted cycloalkyl, cycloalkenyl, optionally substituted phenyl, optionally substituted heterocycle, alkyl sulphony, optionally substituted benzene sulphonyl, an acyl group, or a cation; R<2> is optionally substituted alkyl, alkenyl, optionally substituted cycloalkyl, cycloalkenyl, haloalkenyl, alkynyl, haloalkynyl, optionally substituted phenyl, or optionally substituted heterocycle; R<3> is alkyl, haloalkyl, alkenyl, cycloalkyl, cycloalkenyl, alkynyl, or optionally substituted phenyl; R<4> is alkynyl, haloalkenyl, optionally substituted cycloalkyl, cycloalkenyl, substituted alkyl or optionally substituted heterocycle; R<5> is optionally substituted alkyl, alkenyl, alkynyl haloalkenyl, optionally substituted cycloalkyl, cycloalkenyl or optionally substituted heterocycle; or R<4> and R<5> together with the carbon to which they are attached form a optionally substituted heterocyclic or carbocyclic ring. Intermediates for the production of (2) are also disclosed. The compounds of formula (2) have herbicidal and plant growth regulating properties. |
