Ion-molecule reactions of O,S-dimethyl methylphosphonothioate: evidence for intramolecular sulfur oxidation during VX perhydrolysis.

Abstract

The alkaline perhydrolysis of the nerve agent O-ethyl S-[2-(diisopropylamino)ethyl] methylphosphonothioate (VX) was investigated by studying the ion-molecule reactions of HOO(-) with O,S-dimethyl methylphosphonothioate in a modified linear ion-trap mass spectrometer. In addition to simple proton transfer, two other abundant product ions are observed at m/z… (More)
