DERIVATIVES OF 3-HYDROXY-4-ARYL-5-PIRAZOLINE, PROCESS FOR ITS PREPARATION COMPOSITION OF THE PESTICIDE, PROCESS OF COMBATING ANIMAL PESTS, APPLICATION OF THE MENTIONS OF DERIVED PRODUCTS, PROCESS FOR THE PREPARATION OF PROCESSED COMPOSITES, COMPOUNDED COMPOSITES FOR THE PREPARATION OF HERBICIDAL COMPOUNDS, HALOGENOCARBONYL KETENES, PROCESS FOR THEIR PREPARATION AND ARYLMALONIC ACIDS

摘要

Novel 3-hydroxy-4-aryl-5-oxopyrazoline derivatives of the formula (I) IMAGE are provided, in which A and B are identical or different and independently of one another in each case represent hydrogen, alkyl, alkenyl, alkynyl, alkoxyalkyl, alkylthioalkyl, cycloalkyl or optionally substituted aryl, or A and B together represent the bivalent radical of a saturated or unsaturated and optionally substituted mono-, bi-, tri- or polycyclic system, X represents alkyl, halogen or alkoxy, Y represents hydrogen, alkyl, halogen, alkoxy or haloalkyl, Z represents alkyl, halogen or alkoxy, n represents a number 0, 1, 2 or 3, G represents hydrogen (a) or the groups -CO-R1 (b), IMAGE -SO2-R3 (d), IMAGE or E (g), in which E represents a metal ion equivalent or an ammonium ion, L and M represent oxygen and/or sulphur, and R1, R2, R3, R4, R5, R6 and R7 are as defined in the text of the application. The novel 3-hydroxy-4-aryl-5-oxopyrazoline derivatives of the formula (I) have a particularly pronounced activity against animal pests, in particular against insects and arachnids, and against weeds.
