Contrary to expectation, addition of molecular bromine to 3-thiabicyclohept-6-ene 3,3-dioxide (1) yields substantial amounts of the cis-1,2-dibromide (confirmed by X-ray diffraction), suggesting that the remote SO2 group exerts an extraordinary directive influence by means of a long-range Coulomb interaction that stabilises an open carbocation intermediate at the expense of the usually favoured bridged bromonium ion.
6,7-Dimethylene-3-thiabicycloheptane-3,3-dioxide, a Masked Form of Dendralene and Conjunctive Reagent for Tandem Annelations

, p. 1785 - 1786 (2007/10/02)
Previous limitations of highly reactive dendralene as a tandem annelating reagent in Diels-Alder reactions are overcome by use of its masked form, 6,7-dimethylene-3-thiabicycloheptane-3,3-dioxide (2), and subs
