| abstract |
The present invention relates to: 1. new aminoalkyl esters of the formula (I) <IMAGE> in which R 1 - R 5, X and n have the meaning given in the description. They are prepared by using aminoethanols of the formula II <IMAGE> in which R¹, R², R³, R <4> n and X have the meanings given in the description, or their salts, with carboxylic acids of the formula III R <5> COOH (III) in which R 5 has the meaning given above, or with reactive derivatives thereof, if appropriate in the presence of acid acceptors, if appropriate in the presence of catalysts and if appropriate in the presence of diluents. The invention further relates to intermediates for the preparation of the compounds of the formula I. The new aminoalkyl esters of the formula (I) are notable for high pesticidal, in particular insecticidal activity. |
