The study investigates the synthesis and properties of certain cyclic and bicyclic sulfur compounds. Key chemicals involved include 3-cyclohexenylmethyl p-bromobenzenesulfonate (1), which serves as a starting material. Through a series of reactions, it is converted to 3-cyclohexenylmethyl thioacetate (2). The critical step involves bromination of 2 to yield 3,4-dibromocyclohexenylmethyl thioacetate (3), which upon further reaction with potassium hydroxide in methanol, leads to the formation of endo-4-bromo-6-thiabicyclo[3.2.1]octane (5). Compound 5 is then used to synthesize other derivatives like 6-thiabicyclo[3.2.1]octane (6) via reduction with triphenyltin hydride and azobisisobutyronitrile, and 6-thiabicyclo[3.2.1]oct-3-ene (4) through dehydrobromination with potassium hydroxide in ethylene glycol. The study also examines the dipole moment of 5 and explores its reactivity, noting its unreactiveness in common elimination, displacement, and solvolytic reactions, likely due to steric hindrance from the proximity of sulfur to the bromide.
