    摘要: New cyanoalkylphosphoric acid ester chlorides of the general formula ##STR1## in which R represents a hydrogen atom, an optionally substituted radical selected from alkyl, alkenyl, alkinyl, cycloalkyl, cycloalkenyl, aralkyl, aralkenyl and aryl, or an optionally substituted heterocyclic radical,R.sup.1 represents an optionally substituted radical selected from alkyl, alkenyl, alkinyl, aryl, aralkyl, alkoxy, aryloxy, aralkoxy, alkylthio, alkenylthio, alkinylthio, arylthio, aralkylthio, alkylamino (monoalkylamino or dialkylamino), arylamino or aralkylaminoand X represents oxygen or sulphurare obtained by the reaction of a phosphoric acid dichloride of the general formula ##STR2## with an aldehyde of the general formulaR--CHO (III)in the presence of an approximately equimolar quantity of a water-soluble cyanide. The compounds of the formula (I) can be used as intermediate products for the preparation of insecticides.

    摘要: 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 andR 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 formulaR--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.
