Date Feb. 11, 1988.Compounds of the general formula (2) and isomeric and/or tautomeric forms thereof <IMAGE> (2) characterized in that R1 is selected from the group consisting of: hydrogen; alkyl; alkenyl; alkynyl; cycloalkyl; cycloalkenyl; substituted alkyl or substituted cycloalkyl wherein the alkyl or cycloalkyl group is substituted with a substituent selected from the group consisting of alkoxy, alkylthio, optionally substituted phenyl, optionally substituted heterocycle; optionally substituted phenyl; optionally substituted heterocycle, alkyl sulfonyl; optionally substituted benzene sulfonyl; an acyl group; and an inorganic or organic cation; R2 is selected from the group consisting of: alkyl; alkenyl; cycloalkyl; cycloalkenyl; haloalkenyl; alkynyl; haloalkynyl; substituted alkyl or substituted cycloalkyl wherein the alkyl or cycloalkyl group is substituted with a substituent selected from the group consisting of halogen, alkoxy, alkylthio, optionally substituted phenyl, and optionally substituted heterocycle; optionally substituted phenyl; and optionally substituted heterocycle; R3 is selected from the group consisting of: alkyl; haloalkyl; alkenyl; cycloalkyl; cycloalkenyl; alkynyl; and optionally substituted phenyl; R4 is selected from the group consisting of: alkynyl; haloalkyl; haloalkenyl; cycloalkyl; cycloalkenyl; substituted alkyl or substituted cycloalkyl wherein the alkyl or cycloalkyl group is substituted with a substituent selected from the group consisting of alkoxy, alkylthio, oxo, acyl, alkoxycarbonyl, (alkoxyimino) alkyl, ketal, carboxylic acid optionally substituted phenyl, and optionally substituted heterocycle; and optionally substituted heterocycle; R5 is selected from the group consisting of: alkyl; alkanyl; alkynyl; haloalkyl; haloalkenyl; cycloalkyl; cycloalkenyl; substituted alkyl or substituted cycloalkyl wherein the alkyl or cycloalkyl group is substituted with a substituent selected from the group consisting of alkoxy, alkylthio, oxo, acyl, alkoxycarbonyl, (alkoxyimino) alkyl, betal, carboxylic acid optionally substituted phenyl, and optionally substituted heterocycle; and optionally substituted heterocycle; or R4 and R5 together with the carbon to which they are attached form a substituted or unsubstituted saturated or partially saturated heterocyclic or carbocyclic ring containing 3 or more ring atoms, which ring may be bridged or fused and may contain substituents selected from the group consisting of hydrogen; alkyl; alkenyl; alkynyl; substituted alkyl wherein the alkyl group is substituted with a substituent selected from the group consisting of alkoxy, alkylthio, optionally substituted phenyl, and optionally substituted heterocycle; optionally substituted phenyl; and optionally substituted heterocycle; oxo; acyl; alkoxy; alkylthio; alkoxycarbonyl; (alkoxyimino) alkyl; ketal; and carboxylic acid. The compounds of formula (2) have herbicidal and plant growth regulating properties.
