Catalytic production of sulfur heterocycles (dihydrobenzodithiins): a new application of ligand-based alkene reactivity

Daniel J. Harrison and Ulrich Fekl

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 = S2C2(CF3)2; bdt = S2C6H4). Substituted 2,3-dihydro-1,4-benzodithiins are produced.
