Abstract

The present invention relates to novel N-phenylacetamino nitriles of the general formula (I), ##STR1## in which R.sup.1 represents hydrogen, or represents alkyl, alkenyl, cycloalkyl, aryl or heterocyclyl which are in each case optionally substituted, and PA1 R.sup.2 represents hydrogen, or represents alkyl which is optionally substituted, or PA1 R.sup.1 and R.sup.2, together with the carbon atom to which they are bonded, represent cycloalkyl or heterocyclyl which are in each case optionally substituted, PA1 R.sup.3 represents halogen, alkyl or alkoxy, PA1 R.sup.4 represents hydrogen, halogen, alkyl, halogenoalkyl or alkoxy, PA1 R.sup.5 represents halogen, alkyl or alkoxy, and PA1 m represents a number 0, 1, 2 or 3, processes for their preparation and their use for the preparation of agents for controlling pests.
