| Abstract: | Collision-induced dissociation of the ions [ArS]?, [ArSO]? and [ArSO2]? has uncovered a rich and varied ion chemistry. The major fragmentations of [ArS]? are complex and occur without prior ring hydrogen scrambling: for example, [C6H5S]?→[C2HS]? and [HS]?; [p-CD3C6H4S]?→[C6H4S]?˙, [CD3C4S]? and [C2HS]?. In contrast, all decompositions of [C6H5CH2S]? are preceded by specific benzylic and phenyl hydrogen interchange reactions. [ArSO2]? and [ArSO2]? ions undergo rearrangement, e.g. [C6H5SO]?→[C6H5O]? and [C6H5S]?; [C6H5SO2]?→[C6H5O] ?. The ion [C6H5CH2SO]? eliminates water, this decomposition is preceded by benzylic and phenyl hydrogen exchange. |
