The exceedingly toxic nerve agent VX (O-ethyl S-(2-diisopropylamino(ethyl methylphosphonothioate) cannot be detoxified by reaction with hydroxide ion but is rapidly detoxified by perhydrolysis (substitution with HO2-) presumably via an intramolecular oxygen transfer which precludes loss of the ethoxy group.

ethyl methylphosphonothiolate, VX 1, were investigated with five oxidizingagents. In all the cases, the formation of the VX N-oxide 7 was observed prior to the subsequent oxidation and hydrolysis into the nontoxic O-ethyl methylphosphonate 2. Magnesium monoperoxyphthalate (MMPP) is probably one of the most active reagents to achieve the complete detoxification of VX 1. The decontamination using MMPP
