Summary
  • The synthesis, photochemistry, and photophysics of 17[alpha]-bromo-3[alpha]-(triphenylsilyloxy)-5[alha]-androstan-6-one (1) and 17[beta]-bromo-3[beta]-(triphenylsilyloxy)-5[alpha]-androstan-6-one (2) have been studied in aqueous tetrahydrofuran. The 17[alpha]bromo isomer gives evidence (reduced ([phi].sub.f), ([tau].sub.1), and ([phi].sup.isc) for the ketone) for interaction between the ketone and C-Br moieties in the excited singlet state. Some photodehalogenation is also observed upon excitation of the ketone chromophore. This interaction seems to be absent or minimal for the 17[beta]-bromo isomer. Key words: photodehalogenation, bromosteroid, ketosteroid, intramolecular singlet-singlet energy transfer (ISSET).
