This invention discloses new compounds of the formula ##EQU1## wherein Y is selected from the group consisting of hydrogen, lower alkyl and halogen; R.sup.1 is selected from the group consisting of hydrogen, lower alkyl and lower alkoxy; R.sup.2 is lower alkyl; R.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.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.sup.1 and Z.sup.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.
