Abstract: | The mass spectra of 1,3-dithiane, 2-methyl- and 2,2-dimethyl-1,3-dithiane have been studied by 2H labelling and metastable defocusing. The various molecular ions eliminate S2H. to produce the ions C4H7]+, C5H9]+ and C6H11]+ respectively, each of which scramble the hydrogens either before or accompanying further decomposition. Other processes are complex, but parallel those already reported for 2-aryl-1,3-dithianes. |
