New sulfur-carbon displacement reaction and systematic desulfurization in multi-sulfur linkages of benzopentathiepin

Benzopentathiepin reacts with phosphorus ylides to form a mixture of benzotetrathiepins and benzotrithiins. The carbanion fragment of the phosphorus ylides replaces the one or two sulfur atoms in the multi-sulfur linkages of benzopentathiepin. Systematic desulfurization to form a new cyclic system is accomplished by the use of a combination of phosphorus ylide and triphenylphosphine in the reactions of benzopentathiepin, benzotetrathiepins, and benzotrithiins.
