    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.
