Abstract
The anti-dithietane-1,3-dioxide → syn-dithietane-1,3-dioxide isomerization reaction has been theoretically studied on the frame of MO theory both in the gas phase and in solution. In the gas phase the anti (IIa) ⇔ syn (IIs) equilibrium is slightly displaced to the anti isomer formation. The syn concentration ([Syn]) is ca. 36% in the gas phase, whereas in low polarity solvent, such as carbon tetrachloride, [Syn] is ca. 63%. In medium-high polarity solvents like acetonitrile and dimethyl-sulfoxide the [ anti]/[ syn ] ratio is ca. 0.37.
