Abstract
The effect of different factors (pKa of the base, nature of the counterion and dissociation of the ion pairs) on the course of the base-induced rearrangement of 1,4-dithiins to 1,3-dithiole derivatives is discussed. Ab initio calculations account for the driving force of these isomerisations.
