Novel substituted acetylene-ketones of the formula R.sup.2 --C.tbd.C--CO--R.sup.1 (I) in which R.sup.1 represents optionally substituted cycloalkyl with 4 to 7 carbon atoms or the groupings ##STR1## or represents optionally substituted aryl, if R.sup.2 represents optionally substituted cycloalkenyl or optionally substituted cycloalkylalkyl; R.sup.2 represents alkyl, optionally substituted cycloalkyl, optionally substituted cycloalkenyl, optionally substituted cycloalkylalkyl, optionally substituted aryl or optionally substituted aralkyl; R.sup.3 represents halogen; R.sup.4 represents hydrogen or halogen; R.sup.5 represents alkyl with more than 1 carbon atom, alkenyl, alkinyl or the CHO group or a derivative thereof, or represents methyl, if R.sup.2 represents optionally substituted cycloalkenyl or optionally substituted cycloalkylalkyl; R.sup.6 represents cyano, optionally substituted aryl or the groupings --XR.sup.7 or --CONR.sup.8 R.sup.9 ; R.sup.7 represents alkyl, halogenoalkyl, optionally substituted aryl or optionally substituted aralkyl; R.sup.8 represents hydrogen, alkyl or optionally substituted aryl; R.sup.9 represents hydrogen or alkyl; X represents O, S, SO or SO.sub.2 and the index n represents the numbers 0 or 1. The new compounds are valuable intermediates for the synthesis of substances having plant growth-regulating and fungicidal properties.
