| Abstract: | This article reviews recent studies on gas-phase S N2 ion-molecule reaction by mass spectrometry. The main factors that affect the mechanism, dynamics, stereochemistry and thermodynamics of the gas-phase S N2 ion-molecule reactions are summarized. Through comparision with the same kinds of reaction in condensed phase, the research results not only uncover the most important factors, which determine the direction, stereochemistry and yield of the reaction, but also illuminate the role of solvation in condensed phase reaction. Moreover some unusual reactions are introduced, which take place only in gas phase. The review also discusses some special mass spectrometric methods and techniques in the investigation of gas-phase S N2 ion-molecule reactions. |
