title: Catalytic production of sulfur heterocycles (dihydrobenzodithiins): a new application of ligand-based alkene reactivity.
abstract: Activation of bis-o-phenylene tetrasulfide to render it a practical benzodithiete equivalent for [4+2] cycloadditions with alkenes has been achieved with catalytic amounts of Mo(tfd)(2)(bdt) (tfd = S(2)C(2)(CF(3))(2); bdt = S(2)C(6)H(4)). Substituted 2,3-dihydro-1,4-benzodithiins are produced.
