Abstract
The rates of ring-inversion of six- and seven-membered cyclic trisulfides were investigated by nmr-spectroscopy. The JG#-values are higher than those of the corresponding disulfides. but are not high enough for separation of conformational isomers. At low temperatures the nmr-spectra in some cases show the signals of two different conformers. For certain examples simple symmetry-considerations allow the identification of the actual conformation.
