Mass spectral behaviour of somem-dimethoxybenzene andsym-trimethoxybenzene sulphur derivatives
摘要:
AbstractThe mass spectra of fifteen m‐dimethoxybenzene and sym‐trimethoxybenzene sulphur derivatives (including thiols, sulphides, disulphides and trisulphides) have been investigated. Main fragmentation pathways have been proposed for each class of sulphur compound. Primary skeletal rearrangements of the molecular ions occurring in (poly)sulphur‐bridged derivatives can provide a sensitive diagnostic tool both in structure elucidation and in the problem of locating methoxy substituents.
