  • Herbicidal isoindol-1-one derivatives
    Patent number: 3992189
    Abstract: This invention relates to herbicidal isoindol-1-one derivatives. These compounds have the general formulae: ##SPC1##WhereinR.sub.1 is hydrogen or methyl;R.sub.2 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; andA is --(CH.sub.2).sub.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.
