- Lewis acid-assisted detection of nerve agents in water
-
The five-coordinate compound, Salen(tBu)Al(Ac), prepared in situ from Salen(tBu)AlBr and NH4Ac, forms Lewis acid-base adducts in aqueous solution with the G-type nerve agents, Sarin and Soman, and the VX hydrolysis product, ethylmethylphosphonate (EMPA). The resulting compounds, [Salen(tBu)Al(NA)]+[Ac] - (with NA = Sarin, Soman, and EMPA) are sufficiently stable to be identified by ESI-MS. Molecular ion peaks were detected for every compound with little or no fragmentation. The distinctive MS signatures for the [Salen(tBu)Al(NA)]+ compounds provide a new technique for identifying nerve agents from aqueous solution. The energetics of the displacement of Ac- by the nerve agents to form [Salen(tBu)Al(NA)]+[Ac]- were determined computationally.

A novel chemical compound has a general formula (LX)nY wherein X is selected from a group consisting of a group 13 element other than boron, Y is selected from a group consisting of a halide, a chlorate, a sulfate and a nitrate and L is a chelating ligand containing two nitrogen and two oxygen donor groups where n=1 or 2.
