Insecticidal Activity of Some New Amidophosphoric Acid Esters Containing Substituted Pyridine Moieties

Abstract

Some new amidophosphoric acid esters containing substituted pyridine moieties were synthesized by the reaction of O-aryl, O-ethyl phosphoryl chlorides with 3-(aminomethyl)pyridine and 5-(aminomethyl)-2-chloropyridine. Characterization was done by ¹H NMR, ³¹P{¹H} NMR, IR, MS, and elemental analyses. The results of preliminary bioassay showed that the new compounds possess good insecticidal activity against aphides.

Keywords:
