Insecticidally and acaricidally active novel 1-aryl-3-tert.-butyl-pyrazoles of the formula ##STR1## in which R.sup.1 represents nitro or halogen, R.sup.2 represents halogen or the --NR.sup.3 R.sup.4 group, and also may represent hydrogen when R.sup.1 denotes halogen, where R.sup.3 represents hydrogen, in each case optionally substituted alkyl, alkenyl or alkinyl, and in each case optionally substituted cycloalkyl or cycloalkylalkyl and R.sup.4, independently of R.sup.3, represents the same radicals as R.sup.3l , and, in addition, a ##STR2## radical, where X represents oxygen or sulphur and R.sup.5 represents hydrogen, alkyl, alkenyl, alkinyl, halogenoalkyl, alkoxyalkyl, alkylthioalkyl, optionally substituted cycloalkyl, optionally substituted aryl, alkoxy, alkylthio, optionally substituted aryloxy, optionally substituted arylthio, alkylamino, dialkylamino or optionally substituted arylamino; and Ar represents optionally substituted phenyl, apart from dinitrophenyl, or optionally substituted pyridyl. Intermediates where R.sup.1 is replaced by hydrogen are also new and are also pesticidally active.
具有杀虫和杀螨活性的新型1-芳基-3-叔丁基-吡唑酮的结构式为##STR1##其中,R.sup.1代表硝基或卤素,R.sup.2代表卤素或--NR.sup.3R.sup.4基团,当R.sup.1表示卤素时,也可以表示氢,其中R.sup.3代表氢,每种情况下均为可选择取代的烷基,烯基或炔基,以及可选择取代的环烷基或环烷基烷基,R.sup.4与R.sup.3独立,表示与R.sup.3相同的基团,此外,还有一个##STR2##基团,其中X表示氧或硫,R.sup.5表示氢,烷基,烯基,炔基,卤代烷基,烷氧基烷基,烷硫基烷基,可选择取代的环烷基,可选择取代的芳基,烷氧基,烷硫基,可选择取代的芳氧基,可选择取代的芳硫基,烷基氨基,二烷基氨基或可选择取代的芳基氨基; Ar表示可选择取代的苯基,除去二硝基苯基,或可选择取代的吡啶基。其中,R.sup.1被氢取代的中间体也是新的,并且具有杀虫活性。
