New herbicidally active compounds have the formula ##STR1## wherein R.sup.1 is H, alkyl, alkenyl, cycloalkyl, R.sup.2 is CF.sub.3, NO.sub.2, CN, halogen, alkyl, alkoxy or alkyl, and --X--Y--Z-- is ##STR2## in which R.sup.3 is H, or alkyl, R.sup.4 is H, alkyl or cycloalkyl, R.sup.5 is H or alkyl or when --Y--Z-- contains two vicinal R.sup.4 groups then these R.sup.4 groups taken together with the ring carbon atoms to which they are attached form a saturated or unsaturated hydrocarbyl ring containing 5 or 6 carbon atoms.
