The kinetics of dethionylation of 1,4-dithiin-1-oxides (I-III) in polar solvent like DMSO, sulfolane and chloroform have been studied spectrophotometrically.The reaction shows a pseudo-first order dependence in the substrate.The rate constants for II and III are higher than that of I under similar conditions.The activation parameters suggest an increased solvation in the transition state than in the ground state of the substrate.

Sulphoxide (I) of 2,5-diphenyl-1,4-dithiin when heated in DMSO at 52 deg C furnishes 2,4-diphenylthiophene by extrusion of SO.Sulphoxide (III) of 2,5-diphenyl-3-nitro-1,4-dithiin on similar treatment affords 2,4-diphenyl-3-nitrothiophene.Extrusion of SO f
