Abstract
Abstract This invention discloses new compounds of the formula ##EQU1## wherein Y is selected from the group consisting of hydrogen, lower alkyl and halogen; R 1 is selected from the group consisting of hydrogen, lower alkyl and lower alkoxy; R 2 is lower alkyl; R 3 , R 4 , R 5 , R 6 and R 7 are independently selected from the group consisting of hydrogen and lower alkyl; X is halogen; m is an integer from 0 to 2; Z 1 and Z 2 are independently selected from the group consisting of oxygen and sulfur; and n is an integer from 1 to 2. The compounds of the above description are useful as herbicides.
