Substituted 2-(anilinomethyl)-2-imidazoline derivatives, compositions containing these derivatives, and the use thereof for combating pests

Abstract

Compounds of the formula ##STR1## wherein R.sub.1 and R.sub.2 independently of one another are each a chlorine atom or the methyl group, Y is the group ##STR2## or --CH.dbd.N--R.sub.5, in which R.sub.3 is methyl or ethyl, R.sub.4 is alkyl having 1 to 4 carbon atoms, alkoxy having 1 or 2 carbon atoms, alkylthio having 1 to 4 carbon atoms, or phenyl, X is an oxygen atom or a sulfur atom, and R.sub.5 is an unsubstituted or substituted pyridinyl group which is linked by way of one of its carbon atoms, to the main part of the molecule, and which has substituents selected from the group comprising halogen and alkyl having 1 to 4 carbon atoms, including the acid addition salts thereof, processes for producing the novel compounds by reaction of 2-(anilinomethyl)-2-imidazoline derivatives either with (thio)phosphoric acid dialkyl ester halides or alkyl(thio) phosphonic acid alkyl ester halides, or with N-pyridinylformiminoalkoxy derivatives. The resulting compounds and compositions containing them are effective against members of the order Acarina, and against animal and plant lice, as well as against members of the Calliphoridae family.
