Abstract
Abstract Disclosed are new compounds of the formula ##STR1## wherein R 1 is selected from the group consisting of alkyl, alkenyl, haloalkyl, alkoxy, alkylthio, alkylsulfonyl and alkylsulfinyl; R 2 is selected from the group consisting of alkyl, alkenyl, haloalkyl and ##STR2## wherein R 3 and R 4 are each selected from the group consisting of hydrogen and alkyl; R 5 is selected from the group consisting of hydrogen and alkyl; and R 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.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
151 words
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 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 2 is selected from the group consisting of lower alkyl, lower alkenyl, lower chloroalkyl, lower bromoalkyl, and ##STR17## wherein R 3 and R 4 are each selected from the group consisting of hydrogen and lower alkyl; R 5 is selected from the group consisting of hydrogen and lower alkyl; and R 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.
Claim 2
Dependent Claim
151 words
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 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 2 is selected from the group consisting of lower alkyl, lower alkenyl, lower chloroalkyl, lower bromoalkyl, and ##STR17## wherein R 3 and R 4 are each selected from the group consisting of hydrogen and lower alkyl; R 5 is selected from the group consisting of hydrogen and lower alkyl; and R 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.
Claim 3
Dependent Claim
17 words
