Abstract

During lengthy investigations on acid fluorides in a search for compounds with acaricidal and aphicidal activity, the German chemist, Gerhardt Schrader, became interested in derivatives of orthophosphoric acid. He discovered the first practical insecticide of this general type named “Bladan,” a phosphoric acid ester mixture containing tetraethyl pyrophosphate, which was marketed in Germany in 1943. In 1944 he synthesized the O,O-diethylthionophosphoric acid ester of paranitrophenol and its insecticidal activity was recognized in practice at the beginning of 1945. A patent application was filed in 1948 and by that time firms other than Farbenfabriken Bayer had developed commercial interest in the compound, now known by the common name of parathion. Great interest in parathion-type compounds was stimulated by their outstanding insecticidal properties and very broad spectrum of activity. During the 1950s a number of alkyl(thio) esters of phosphoric acid were developed commercially as insecticides in Europe, USA, and elsewhere and Schrader (1963) described 49 in his book Die Entwicklung neuer insektizider Phosphorsäure-Ester.
