The title compound, the condensation product of sulfur dichloride and 1,5-cyclooctadiene, is a reliable acceptor of a wide variety of heteroatom nucleophiles, sometimes in reversible fashion. Optical resolution of the core structure has been achieved and preserved in succeeding transformations. The high reactivity and reliable stereochemical control afforded by this system illustrates the power of neighboring-group participation by the sulfur center.
