    Tritiation of organic compounds by polymer-supported base catalysts
    摘要:
    利用聚合物支撑的碱催化剂,通过氢同位素交换反应对一系列有机化合物进行了氚化(有时还进行了脱氚)。某些市售阴离子交换树脂的热稳定性较差,限制了它们作为氚化催化剂的使用,通过制备更稳定的聚合物支撑吡啶鎓盐,这一问题得到了解决。阴离子交换树脂对活性很高的氚化水和活性很低的氚化水同样有效,而且可以成功标记含有硝基的化合物,因为硝基会毒害金属催化的交换反应。

  • Tritiation of organic compounds by polymer-supported base catalysts
    作者:J. R. Brewer、J. R. Jones、K. W. M. Lawrie、D. Saunders、A. Simmonds

    A range of organic compounds have been tritiated (and in some cases deuteriated) via hydrogen isotope exchange reactions using polymer supported base catalysts. The problem of poor thermal stability of some commercially available anion exchange resins, which limits their use as tritiation catalysts, has been overcome by the preparation of a more stable polymer supported pyridinium salt. The anion exchange resins are as effective at very high activities of tritiated water as they are at low and compounds containing nitro groups, which poison metal-catalysed exchange reactions, can be successfully labelled.

    measured secondary isotope effects on the deuteroxide ion-catalyzed proton exchange of acetophenone are kH/kD = 1.08 ± 0.07 for α-CH3 exchange and kH/kD = 0.96 ± 0.08 for α-CH2D exchange. For α-CH2T exchange in water, the corresponding secondary isotope effect is kH/kD = 1.06 ± 0.02, assuming the rule of the geometric mean is valid. These effects are smaller than the calculated equilibrium isotope effect

    Specific features of the stepwise hydrogen exchange mechanism and transition state structure in the systems acetophenone-liquid ammonia in the absence of foreign compounds and in the presence of bases and toluene-liquid ammonia in the presence of potassium amide were studied in terms of an approach based primary and secondary kinetic isotope effects of the substrate and the solvent. The mechanisms of reactions involving acetophenone and toluene were compared. In the first case, an elementary act of CH-acid ionization is contributed to a small extent by diffusion-controlled separation of the carbanion and ammonia molecule. hydrogen exchange in toluene is characterized by complete absence of the internal ion pair return effect. The ratio k(D)(NH3)/k(T)(NH3) for hydrooen exchange in acetophenone tends to decrease on addition of bases (with simultaneous increase in its rate), which may be explained by formation of an adduct via interaction between the unshared electron pair on the heteroatom in the base molecule and the carbonyl carbon atom. The anomalous temperature dependence of k(D)(NH3)/k(T)(NH3) for hydrogen exchange in toluene is interpreted as a result of contribution of side metalation of the C-H bond by potassium amide. The change in the solvent protophilicity due to replacement of the "light" solvent by deuterated one differently affects the kinetics and mechanism of hydrogen exchange in acetophenone and toluene. Measurements of the alpha-deuterium effect gave information on the mode of angular deformation of C-D bonds in the methyl group of toluene in the hydrogen exchange transition state.
