  摘要：

  通过使用 VV 或 MoVI 催化的有机底物氧溴化的两相程序，已经分离和表征了金刚烷亚金刚烷溴鎓盐（ADABr+X–；X– = VV 和 MoVI 的阴离子）。证明这些盐相对于相应的三溴化物衍生物明显更稳定。

  A dynamic H-1 NMR study of the adamantylideneadamantane (Ad=Ad)/Br2 system has been undertaken in d4-1,2-dichloroethane as a function of excess [Br2] and temperature. Bromine site exchange rate constants (k(NMR)) were determined by line shape analysis of the spectral region between delta 2.1 and 2.6. The temperature range between the fast and slow exchange limits for a given [Br2] is unusually narrow, being approximately 15-degrees-C. Increasing [Br2] at a given temperature dramatically reduces the k(NMR) due to the equilibrium formation of Br3-, Br5- and Br7-/bromonium ion pairs. It is shown that the dynamic phenomena proceed via the rate-limiting dissociation of a 1:1 charge-transfer complex to free Ad=Ad + Br2. General implications for the bromination of more reactive olefins are discussed.
