Abstract
The electron ionization mass spectra of substituted (β-hydroxy)sulfides, -sulfones, and their corresponding acetates of the 1,3-dioxepane series were studied. The main regularities in the pathways of fragmentation of their molecular ions were revealed. It was shown that during electron ionization, the main directions of decomposition of the studied compounds are due to the elimination of substituents in the 1,3-dioxepane ring. For 6-phenylthio-1,3-dioxepanes and 6-phenylsulfonyl-1,3-dioxepanes, the formation of ions associated with the breaking of C-S bonds with charge localization on the sulfur-containing fragment is observed.
