ABSTRACT:
Cyclohexane-1,3-dione derivatives of the formula ##STR1## where R.sup.1 is alkyl of from 2 to 4 carbon atoms, R.sup.2 is alkyl, unsubstituted or halogen-substituted alkenyl, or alkynyl, each of from 2 to 5 carbon atoms, R.sup.3 is a saturated or unsaturated hydrocarbon radical of up to 4 carbon atoms which is unsubstituted or substituted by 1 to 3 hydrocarbon radicals of a total of up to 8 carbon atoms, by aryl of from 6 to 10 carbon atoms, or by benzyl, R.sup.4 is, when R.sup.3 is unsaturated or olefinically or aromatically substituted, alkyl of from 1 to 6 carbon atoms, R.sup.4 is further unsubstituted or halogen-substituted alkenyl of from 2 to 6 carbon atoms, alkynyl of from 2 to 6 carbon atoms, naphthyl, arylalkyl or arylalkenyl, where aryl is of from 6 to 10 carbon atoms and is unsubstituted or substituted by alkyl or alkoxy, each of from 1 to 3 carbon atoms, or by halogen, and where alkyl or alkenyl is of from 2 to 3 carbon atoms, at least 2 of which being between aryl and sulfur, Z is H, CN, CH.sub.3, methoxycarbonyl or ethoxycarbonyl, and n is 0,1 or 2, and salts thereof.
