    Description: Nucleophilic displacement reactions (the SN2 reaction) of ions in the gas phase are a prototypical reaction system that allows a study of dynamics, mechanisms, and structure-energy relations. This article reviews aspects of the kinetics (especially the applicability of statistical reaction rate theory), the relation of structure and reactivity, and the effects of small numbers of solvent molecules on the reaction and compares the behavior of the ionic reaction in the gas phase with that in solution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chabinyc -- Craig -- Regan -- Brauman -- New York, N.Y. -- Science. 1998 Mar 20;279(5358):1882-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉M.

    Description: Rates of SN2 reactions of chloride ion with methyl- and tert-butyl-substituted chloroacetonitrile were measured by using Fourier transform-ion cyclotron resonance spectrometry to follow the isotopic exchange reaction. Barrier heights for these reactions indicate that steric effects in the gas phase are diminished relative to apparent steric effects in solution. We attribute the increased barrier in solution to a solvation effect. Monte Carlo simulations done using statistical perturbation theory confirm that steric hindrance to solvation contributes to SN2 barriers in solution.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Regan, Colleen K -- Craig, Stephen L -- Brauman, John I -- New York, N.Y. -- Science. 2002 Mar 22;295(5563):2245-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry, Bryn Mawr College, Bryn Mawr, PA 19010, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11910104" target="_blank"〉PubMed〈/a〉
