Argon ions reaction with hydrogen

Frimer, A. A., J. Org. Chem., 1977, 42, 3194-3196, footnote 7 A new method of preparation involves interaction of ally lie halides in solvents with 98% hydrogen peroxide in presence of silver ion and base at ambient temperature under argon. The reactions must be run in the dark to prevent precipitation of metallic silver, which will catalyse decomposition of the hydroperoxide or excess hydrogen peroxide. In an experiment not run in the dark, the hydroperoxide from 3-chlorocyclohexene ignited spontaneously after isolation and concentration.

The argon-hydrogen and krypton-hydrogen systems are distinguished by the fact that the reaction occurs with comparable cross-sections via both hydrogen molecule ion and rare gas ion reactants— namely,... 

The ionization energies of hydrogen (15.4 eV) and argon (15.8 eV) are higher than those of silane (11.6 eV) and disilane (9.9 eV). Therefore, ion-molecule reactions of H2 or Ar+ with silane or disilane will result in electron transfer from... 

In another approach to reduce the energy spread of ions produced in the plasma source and remove polyatomic interferences, a hexapole collision cell (see also Chapter 2) is placed in front of the magnetic field. Argon, helium, or hydrogen gas is introduced into the cell, where ions from the plasma collide with the gas. Interaction between ions and the gas causes the ions to lose kinetic energy and polyatomic species formed in the plasma are decomposed as a result of ion-molecule collisions and/or, in the case of H2, chemical reactions. The collision cell will attenuate most interferences by several orders of magnitude.
