  • Bromination of Norbornene: the Question of Bromonium Ions <i>vs</i>. 6,1-Hydride Shift
    作者:D. R. Marshall、P. Reynolds-Warnhoff、E. W. Warnhoff、J. R. Robinson

    日期:1971.3.15
    a radical mechanism. The product composition from the bromine addition has been compared with that of the analogous chlorination and bromofluorination reactions. Degradation of the 2-exo,3-endo-dibromonorbornane from bromination of 5,6-14C-norbornene has shown that this dibromide is formed by two ionic routes: (a) from a bromonium ion 14 (or its equivalent), and (b) from the cation 12 formed by 6,1-hydride
    对降冰片烯 (1) 与溴的反应进行了重新研究,发现除了溴代降冰片烯 (2) 和 2-外型溴代降冰片烷 (20) 之外,还会产生一种复杂的二溴化物混合物,其中已分离出五种 (15-19)并确定。已发现这些二溴化物是离子加成的动力学控制产物。显然,二溴化物 15 也在一定程度上通过自由基机制在四氯化碳中形成。溴加成的产物组成与类似的氯化和溴氟化反应的产物组成进行了比较。2-exo,3-endo-dibromonorbornane 从 5,6-14C-降冰片烯的溴化中降解表明,这种二溴化物是通过两种离子途径形成的:(a)从溴离子 14(或其等价物),和( b) 由 6,1-氢化物转变形成的阳离子 12。

Three isomeric bromochloronorbornanes (2-endo-bromo-3-exo-chloro-, 2-exo-bromo-3-endo-chloro-, and 2-exo-bromo-7-syn-chlorobicyclo[2.2.1.]heptanes), 2-exo-7-syn- and 2-exo-7-anti-dibromo- and-dichloronorbornanes, and 2-bromonortricyclane were isolated and characterized by1H and13C NMR spectra. The spectral and structural characteristics of the resulting

    containing 40–43% of pyridine rings, were transformed with bromine to provide three types of brominating agents (1), (2), and (3). Reactions of cis- and trans-1-phenylpropene with (1), (2), and (3) resulted in a high degree of anti-stereoselectivity. The reactivity increases from (1) to (3); solvent polarity has no significant effect on stereoselectivity, but affects the reactivity, being significantly greater

  • A NEW METHOD FOR MIXED HALOGENATION. N-CHLOROAMINE-PHOSPHORUS BROMIDE SYSTEM AS A SYNTHETIC EQUIVALENT OF THE MIXED HALOGEN Cl<sup>+</sup>Br<sup>−</sup>
    作者:Nikolai V. Zyk、Elena K. Beloglazkina、Vladimir S. Tyurin、Nikolai S. Zefirov
    DOI:10.1080/10426509808035682
    日期:1998.8.1
    A new method for the mixed halogenation of alkenes has been proposed based on the reaction of olefins with N-chloroamines in the presence of phosphorus bromide or oxybromide. The plausible reaction mechanism and the results of reactions with a number of model unsaturated compounds such as cyclohexene, 1-heptene. ethyl cinnamate, norbornene and those from the bicyclo[2.2.1]heptane series are discussed. In the reactions with reactive olefins this reagent acts as a synthetic equivalent of the unknown mixed halogen [Cl+Br-] with "abnormal" polarity of halogen atoms. The same reactions activated by PCl3 or POCl3 result in dichlorides in yields near to quantitative.
