Abstract

The structures and energies of 1,2,7-thiadiazepane 1,1-dioxide and the axial and equatorial conformers of 1,2,7-thiadiazepane 1-oxide were calculated using the hybrid density functional B3LYP with the cc-pVDZ basis set. The results obtained explain the lower stabilities of equatorial conformers compared to the axial analogs and the lower stabilities of sulfones compared to sulfoxides.
