Abstract
Abstract This invention discloses new compounds of the formula ##STR1## 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 and R 4 are independently selected from the group consisting of hydrogen and lower alkyl; X is halogen; and n is the integer 1 or 2. The compounds of the above description are useful as herbicides.
