Patent number: 4771066
Abstract: Insecticidally and acarididally active 1-arylpyrazoles of the formula ##STR1## in which R.sup.1 represents hydrogen, alkyl or halogen alkyl,R.sup.2 represents alkyl, alkenyl, alkinyl, cycloalkyl, halogenoalkyl, halogenoalkenyl, alkoxyalkyl, alkylthioalkyl, alkylsulphinylalkyl, alkylsulphonylalkyl, optionally substituted aralkyl or optionally substituted aryl,R.sup.3 represents alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenyl, alkoxyalkyl, alkylthioalkyl, cycloalkyl or optionally substituted aralkyl,R.sup.4 represents alkyl, alkenyl, alkinyl, halogenoalkyl, halogenoalkenyl, alkoxyalkyl, alkylthioalkyl, cycloalkyl or optionally substituted aralkyl, and, in addition, also represents hydrogen in the case where R.sup.3 does not simultaneously represent unsubstituted alkyl, orR.sup.3 and R.sup.

Patent number: 4770693
Abstract: Herbicidally active novel substituted 5-acylamino-1-phenylpyrazoles of the formula ##STR1## in which R.sup.1 represents cyano, alkoxycarbonyl, alkenyloxycarbonyl, alkinyloxycarbonyl, aminocarbonyl, alkylaminocarbonyl, alkenylaminocarbonyl or alkinylaminocarbonyl,R.sup.2 represents hydrogen, alkyl, alkenyl, alkinyl, optionally substituted cycloalkyl, alkoxyalkyl, alkylthioalkyl, halogenoalkyl or optionally substituted aryl andR.sup.3, R.sup.4, R.sup.5, R.sup.6 and R.sup.7, which are identical or different, represent hydrogen, halogen, cyano, nitro, alkyl, alkoxy, alkylsulphonyl, alkoxycarbonyl or a radical --R.sup.8,whereinR.sup.8 represents halogenoalkyl, with the proviso that at least one of the radicals R.sup.3, R.sup.4, R.sup.5, R.sup.6 or R.sup.7 represents a radical --R.sup.8, but R.sup.1 does not represent cyano if R.sup.5 represents trifluoromethyl. Many of the intermediates are also novel.
