The application of the Ramberg-Backlund reaction in the conversion of several 3,n-dithiabicycloalkatrienes to the corresponding bicycloalkapentaenes is reported.Proton magnetic resonance and ultraviolet spectra were utilized in the overall characterization of bicyclotetradeca-2,8,10,12,1(14)-pentaene, bicyclopentadeca-2,9,11,1(15)-pentaene, and their precursors.The final step in the synthesis was a Ramberg-Backlund of a bis-α,α'-chloro sulfone.The intermediate, 2-chloro-3-thiabicyclopentadeca-9,11,13,1(15)-tetraene-3,3-dioxide, was isolated and characterized.The structure and stability of the bridged α,α'-dichloro sulfide intermediates were examined.
