Simple and practical one-step synthesis of new 1,3-dienic d-sultones from terminal alkynes and some synthetic applications of these compounds

1,3-Dienic d -sultones 4,6-diaryl-[1,2]oxathiine 2,2-dioxides were synthesized via a one-step reaction of arylalkynes with dioxane sulfotrioxide. The reactivity of various alkynes in this reaction was investigated. The resulting sultones were brominated with Br2 or N-bromosuccinimide regioselectively a to sulfur and subsequently coupled with phenylacetylene using Sonogashira conditions.
