Abstract

Compounds of the formula ##STR1## wherein X is a hydrogen atom, a halogen atom, a trihalomethyl group, an alkyl group, or a cyano group, Y is a hydrogen atom, or a trihalomethyl group, and Z is an alkoxy group, an alkoxyalkoxy group, a hydroxyalkoxy group, an alkyl group, a halogen atom, an alkylamino group, a dialkylamino group, an alkylthio group, a carboxy group, a carbalkoxy group, a carboxyalkoxy group, a carbalkoxyalkoxy group, a carboxyalkyl group, a carbalkoxyalkyl group, a dialkylureido group, an alkanoylamino group, or carbalkoxyamino group, and compositions containing these compounds exhibit herbicidal activity.

We claim: .[.1. A compound of the formula ##STR6## wherein X is a hydrogen atom, a halogen atom, a trifluoromethyl group, or a (C 1  -C 4 )alkyl group, 
     
        carbalkoxyalkyl group having up to 6 carbon atoms..]. .[.2.  A compound according to claim 1 wherein Y is a hydrogen atom..]. .[.3. A compound 
     
     
        according to claim 2 wherein X is a halogen atom..]. 4. A compound according to claim .[.3.]. .Iadd.9 .Iaddend.wherein Z is a carbalkoxy 
     
     
        group. 5. A compound according to claim 4 wherein X is a chlorine atom and Z is a carbomethoxy group. .[.6. A compound according to claim 1 wherein X is a halogen atom, Y is a halogen atom, and Z is a carbalkoxy group..]. 
     
     
        .Iadd.7.  A compound of the formula: ##STR7## wherein Z is a carbalkoxy group having 1 to 4 carbon atoms in the alkoxy 
     
     
        moiety. .Iaddend. .Iadd.8.  A compound of the formula: ##STR8## 
     
     
        .Iaddend. .Iadd.9.  A compound of the formula ##STR9## wherein X is a halogen atom and Z is a carboxy group or a carbalkoxy group having up to 4 carbon atoms in the alkoxy moiety. .Iaddend.
