- W165655582 abstract "Methods for the synthesis of 0-aryl 0-alkyl S-alkyl phosphorothioates (I) based on reaction of alkyl-sulfenylchlorides with phosphites and on dealkylation-alkylation reaction of phosphorothionates were studied. The biological properties of several hundred synthesized compounds allow the following conclusions: 1. Compounds I where 0-alkyl = 0-ethyl and S-alkyl = S-n-propyl, have the best insecticidal as well as favourable toxicological properties. 2. The aryl group in I can be widely varied showing an activity maximum and toxicity minimum for the halogenated aryls. In laboratory and field tests excellent results were obtained with 0-(4-bromo-2-chloro-phenyl)0-ethyl S-n-propyl phosphorothioate (profenofos) as an insecticide. The difference in activity spectrum between I and the 0-aryl 0,0-diethyl phosphorothionates shows that there is still an innovative potential in organophosphorus chemistry." @default.
