New phenoxypyridylmethyl esters of the general formula ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 have the meaning given in the description and R represents the radical ##STR2## wherein R.sup.4 and R.sup.5 have the meaning given in the description, and represents the radical ##STR3## wherein R.sup.6 and R.sup.7 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 ##STR4## wherein R.sup.1, R.sup.2 and R.sup.3 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.
通式为##STR1##的新苯氧吡啶基甲酯,其中R.sup.1、R.sup.2和R.sup.3的含义如描述中所述,R代表基团##STR2##其中R.sup.4和R.sup.5的含义如描述中所述,并代表基团##STR3##其中R.sup.6和R.sup.7的含义如描述中所述,通过以下过程获得:将通式为R--COOH(II)的羧酸(其中R的含义如前述)或这些酸的反应衍生物与通式为##STR4##的苯氧吡啶醇(其中R.sup.1、R.sup.2和R.sup.3的含义如上所述)或这些醇的反应衍生物反应,如适当时在酸受体的存在下,如适当时在催化剂的存在下,如适当时在稀释剂的存在下。通式(I)的新苯氧吡啶基甲酯具有高杀虫活性,特别是对昆虫和蜱类有杀灭作用。
