Es wurde gefunden, daß sich neutrale Ester der Thiolphosphorsäure folgender ZusammensetzungIt has been found that neutral esters of thiolphosphoric acid have the following composition
R1O,R 1 O,
R2O'R 2 O '
P-S-R3 PSR 3
(R1 und R2 stehen für beliebige Alkylreste, R3 steht ίο für einen beliebig substituierten Arylrest) hervorragend zur Bekämpfung von saugenden und fressenden Insekten aller Art eignen. Die genannten Ester sind z. B. durch Umsetzung von Dialkoxyphosphorsäurechloriden mit Thiophenolen nach an sich bekanntem Verfahren erhältlich.(R 1 and R 2 stand for any alkyl radicals, R 3 stands for any substituted aryl radical) excellent for combating sucking and eating insects of all kinds. The esters mentioned are z. B. obtainable by reacting dialkoxyphosphoric acid chlorides with thiophenols by a method known per se.
Die neuen Ester können als Staub oder, vermischt mit einem Emulgator und Wasser, als Emulsionen zur Anwendung gebracht werden. Folgende Beispiele mögen das Gebiet der Erfindung erläutern:The new esters can be used as dust or, mixed with an emulsifier and water, as emulsions can be applied. The following examples may illustrate the field of the invention:
