Hydrolysis and Phytotoxic Activity of Cyclic Imides

In order to explain the close phytotoxic activities of N-aryl-3,4,5,6-tetrahydrophthalimides and their hydrolyzed products, N-aryl-3,4,5,6-tetrahydrophthalamic acids, five sets of both types of compounds possessing the same aryl residues were prepared.Their phytotoxic activity against sawa millett (E. utilis) and green microalga (S. acutus), and the relationship of interconversion between the imides and amide acids during the bioassay were investigated.In almost all cases, the imides showed stronger activity than the corresponding amide acids.The hydrolysis of the imides and the cyclization of amide acids were observed in respect of the aryl residues.The phytotoxicity caused by the imides and amide acids tested was influenced by this interconversion.

Herbicidal 2-fluoro-4-halo-phenyl-4,5,6,7-tetrahydro-2H-isoindole-1,3-diones

This invention relates to herbicidal 2-fluoro-4-halo-phenyl-4,5,6,7-tetrahydro-2H-isoindole-1,3-diones. These compounds may be used for selective weed control in certain crops or for total vegetation control.

Herbicidal 2-substituted aryl-4,5,6,7-tetrahydro-2H-isoindole-1,3-diones

This invention relates to herbicidal 2-substituted aryl-4,5,6,7-tetrahydro-2H-isoindole-1,3-diones. These compounds may be used for selective weed control in certain crops or for total vegetation control.

Herbicidal isoindol-1-one derivatives

This invention relates to herbicidal isoindol-1-one derivatives. These compounds have the general formulae: SPC1 Wherein R1 is hydrogen or methyl; R2 is hydrogen or alkyl of 1 to 4 carbons; X is fluorine, chlorine or bromine; Y is hydrogen or fluorine; Z is hydrogen or fluorine, provided that when Y and Z are both fluorine, X must also be fluorine; and A is --(CH2)4 -- or --CH=CH--CH=CH--, provided that when A is --CH=CH--CH=CH-- and Y is hydrogen, Z must be fluorine. Both geometric isomers, Formulae IIa and IIb, are encompassed by this invention. In particular, these compounds have demonstrated that they are active pre- and post-emergence herbicides and tend to do minimal damage to certain desirable crops, e.g., corn and wheat.
