Polysulfide synthesis via visible-light-induced heteroarene-migratory dithiosulfonylation reaction.

A photocatalyzed heteroarene-migratory dithiosulfonylation of alkene-tethered sulfone using dithiosulfonate (ArSO-SSR) has been reported, featuring mild conditions, and high atom economy. The resulting products can be converted into dihydrothiophenes and homoallyl disulfides, making the method highly valuable.
