Products of reaction of tricyclo[4.1.0.02,7]heptane and 1-bromotricyclo[4.1.0.02,7]heptane with hydrogen sulfide, and syntheses based thereon

By reactions of 1-R-tricyclo[4.1.0.0(2,7)]heptanes (R = H, Br) with hydrogen sulfide initiated by UV irradiation endo-6-bicyclo[3.1.1]heptanethiols and bis(endo-6-bicyclo[3.1.1]heptyl) sulfides were synthesized. The sulfides were oxidized to the corresponding sulfoxides and sulfones. The results of HBr elimination from the bromine-substituted sulfoxides and sulfones effected by potassium tert-butylate are discussed. The latter reaction results in the recovery of the system of I-substituted tricyclo[4.1.0.0(2,7)]heptane.
