The gas-phase ion-molecule chemistry of H2P(-) has been investigated by using the flowing afterglow technique.Generated by proton abstraction from PH3 by H2N(-) or OH(-), H2P(-) reacts with N2O, CO2, OCS, CS2, O2, NO2, SO2, CH3X, and (CH3)3SiCl to yield a variety of ion products.Products usually arise from initial nucleophilic attack of H2P(-) on the neutral, followed by intramolecular proton transfer and/or expulsion of a neutral fragment.Many of the reactions are similar to those for H2N(-), though differences are attributable to the weaker nucleophilicity of H2P(-).Product branching ratios and reaction rate constants are reported, and possible mechanistic pathways are discussed.
