The invention relates to novel herbicidal compounds of the formula I or I' ##STR1## in which X is an oxygen or sulfur atom, R.sup.1 is H, C.sub.1 -C.sub.6 -alkyl, C.sub.2 -C.sub.6 -alkenyl, C.sub.2 -C.sub.6 -alkynyl, C.sub.1 -C.sub.6 -haloalkyl, (C.sub.1 -C.sub.4 -alkoxy-C.sub.1 -C.sub.4 -alkyl, (C.sub.1 -C.sub.6 -alkoxy)carbonyl, aryloxycarbonyl, (C.sub.1 -C.sub.6 -alkyl) aminocarbonyl, arylaminocarbonyl, phenyl, substituted phenyl or acyl, R.sup.2 is phenyl or substituted phenyl, R.sup.3 independently of other radicals R.sup.3 is H or C.sub.1 -C.sub.5 -alkyl and n is an integer from 0 to 6. The herbicides are suitable for selectively controlling harmful plants in cereal crops.
