摘要

Insecticidally active novel substituted malonic acid diamide insecticides of the formula IMAGE wherein R1 represents aryl or heteroaryl, each of which can optionally be substituted, R2 represents hydrogen or trialkylsilyl, and represents alkyl, cycloalkyl, alkenyl, alkinyl, aralkyl, alkylcarbonyl, arylcarbonyl, alkoxycarbonyl, aryloxycarbonyl, alkylsulphenyl, arylsulphenyl, alkylsulphonyl, arylsulphonyl, alkylaminosulphonyl, dialkylaminosulphonyl, arylaminosulphonyl or arylalkylaminosulphonyl, each of which can optionally be substituted, and represents radicals of the formula -CO-NR5R6 wherein R5 and R6 independently of one another represent hydrogen, alkyl, cycloalkyl, aryl, alkylaminocarbonyl, arylaminocarbonyl, alkylcarbonyl, arylcarbonyl, alkoxycarbonyl, aryloxycarbonyl, alkylsulphonyl or arylsulphonyl, it being possible for these radicals to be optionally substituted, R3 represents hydrogen or the radical R4, R7 and R8 independently of one another represent hydrogen, alkyl or aryl, and R4 represents a radical of the formula -CH2-R9 and R9 represents hydroxyl, alkoxy or aryloxy, each of which is optionally substituted, and alkylamino, arylamino, aralkylamino, dialkylamino, diarylamino, cycloalkylamino, alkenylamino, or nitrogen-containing saturated heterocyclic radicals which are bonded via N and which optionally contain further hetero atoms.
