The initial fragmentation of the molecular ions of 5-aryl-4,6-bis(methoxycarbonyl)-1,3-dithiane 1,1,3,3-tetroxides is characterized by two parallel processes, i.e., the formation of (M - 64)/sup +/ ions by the simultaneous elimination of a sulfur dioxide molecule and the appearance of (M - 31)/sup +/ ions, the formation of which is accompanied by the elimination of the methoxyl radical. Isomerization of the molecular ions of 5-phenyl-1,3-dithiane 1,1,3,3-tetroxide to the cyclic sulfinate is not observed, and the main process in its initial dissociation involves the successive elimination of SO/sub 2/ groups and the appearance of (M - 64)/sup +/ and (M - 128)/sup +/ ions. The (M - SO)/sup +/ and (M - SO - H)/sup +/, the appearance of which is characteristic of the sulfone-sulfinate rearrangement of linear and cyclic monosulfones, were not detected.
