Abstract

Abstract The present invention is directed to herbicidal compounds of the formula ##STR1## wherein each R 1 independently is halogen; R 2 is halo or trifluoromethyl; and n is 1-5; with the provisos that when n is 1, R 1 is other than fluorine, and when n is 2 and each R 1 is chlorine, at least one R 1 is located at a para or ortho position on the phenyl ring.
