✦ Synopsis

The reactions of the atomic oxygen radical anion O(-) with CH3-S-CH2-CN m the gas phase have been examined with Fourier transform ion cyclotron resonance in combination with tandem mass spectrometric experiments performed with a double-focusing quadrupole hybrid instrument. Deuterium labeling has revealed that the O(-) ion reacts with CH3-S-CH2-CN by proton abstraction from the methylene group as well as by competing 1,1- and 1,3-H 2 (+) abstractions to afford isomeric radical anions. High kinetic energy (8 keV) collision-induced charge reversal experiments indicate that the 1,1-H 2 (+.) -abstraction leads to a [Formula: see text] carbene ion, whereas the 1,3-H 2 (+) abstraction yields a novel sulfur-containing distonic radical anion, which is formulated as [Formula: see text].
