PHENOXYPYRIDYLMETHYL ESTERS, A PROCESS FOR THE PREPARATION AND THEIR USE IN PEST COMBATING AGENTS

摘要

New phenoxypyridylmethyl esters of the general formula (I) wherein R1, R2 and R3 have the meaning given in the description and R represents the radical wherein R4 and R5 have the meaning given in the description, and represents the radical wherein R6 and R7 have the meaning given in the description, are obtained by a process in which carboxylic acids of the general formula R-COOH (II) wherein R has the meaning given previously, or reactive derivatives of these acids, are reacted with phenoxypyridyl alcohols of the general formula (III) wherein R1, R2 and R3 have the meaning given above, or with reactive derivatives of these alcohols, if appropriate in the presence of acid acceptors, if appropriate in the presence of catalysts and if appropriate in the presence of diluents. The new phenoxypyridylmethyl esters of the formula (I) are distinguished by a high pesticidal, particularly insecticidal and acardicidal activity.
