Dibromotetrachloroethane (C(2)Br(2)Cl(4)) is demonstrated as a halogenating reagent for the one-pot conversion of sulfones to alkenes by way of the Ramberg-Bäcklund rearrangement. Dibromotetrachloroethane successfully replaces known ozone depleting agents CCl(4), CBr(2)F(2) and C(2)Br(2)F(4). A formal synthesis of E-resveratrol is demonstrated
