The mass spectra of thietane, trimethylene sulfoxide, and trimethylene sulfone are reported. The major competing reactions are four-center fragmentation, heteroatom group elimination and rearrangement. The oxidation state of the sulfur atom has a profound effect upon the competition among these reaction ...
