Abstract
Disclosed are new compounds of the formula ##STR1## wherein R.sup.1 is selected from the group consisting of alkyl, alkenyl, haloalkyl, alkoxy, alkylthio, alkylsulfonyl and alkylsulfinyl; R.sup.2 is selected from the group consisting of alkyl, alkenyl, haloalkyl and ##STR2## wherein R.sup.3 and R.sup.4 are each selected from the group consisting of hydrogen and alkyl; R.sup.5 is selected from the group consisting of hydrogen and alkyl; and R.sup.6 is selected from the group consisting of alkyl, cycloalkyl and ##STR3## WHEREIN X is selected from the group consisting of alkyl, halogen, haloalkyl and alkoxy, and n is an integer from 0 to 3. The subject compounds are useful as herbicides.
Claims2
A herbicidal composition comprising an inert carrier and, as an essential active ingredient, in a quantity toxic to weeds, a compound of the formula ##STR16## wherein R.sup.1 is selected from the group consisting of lower alkyl, lower alkenyl, lower chloroalkyl, lower bromoalkyl, trifluoromethyl, lower alkoxy, lower alkylthio, lower alkylsulfonyl and lower alkylsulfinyl;
- R.sup.2 is selected from the group consisting of lower alkyl, lower alkenyl, lower chloroalkyl, lower bromoalkyl, and ##STR17## wherein R.sup.3 and R.sup.4 are each selected from the group consisting of hydrogen and lower alkyl;
- R.sup.5 is selected from the group consisting of hydrogen and lower alkyl;
- and R.sup.6 is selected from the group consisting of lower alkyl, cycloalkyl of from 3 to 7 carbon atoms, and ##STR18## wherein X is selected from the group consisting of lower alkyl, lower alkoxy, halogen and lower haloalkyl, and n is an integer from 0 to 3.
