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.
Convenient synthesis of 1,2,4-benzotrithiins from benzopentathiepin with phosphorus ylide

Novel 1,2,4-benzotrithiins were synthesized in satisfactory yields by treatment of benzopentathiepin with alkylidenephosphoranes. In this reaction, benzopentathiepin was found to serve as a 1,5-dipole synthon.
