  1H,13C and15N NMR and IR studies of halogen-substituted tetrazolo[1,5-a]pyridines

  摘要：

  The tetrazole-azide tautomerization of some halogen-substituted tetrazolo[1,5-a]pyridines was examined by IR spectroscopy at ambient temperature and by H-1,C-13 and N-15 NMR spectroscopy at various temperatures. The tetrazolopyridines can exhibit equilibrium between the azide and the tetrazole forms. For some of them slow exchange occurs on the NMR time-scale, such that it is possible to estimate equilibrium constants. The position and nature of the substituent in the pyridine ring result in stabilization or destabilization of the tetrazole form and exert a strong influence on the values found for the equilibrium constants. A saturation transfer experiment was carried out for 5-bromotetrazolo[1,5-a]pyridine and the rate constants were estimated. Moreover, based on the van't Hoff equation, the enthalpy Delta H degrees and entropy Delta S degrees for the tautomerization were calculated. Ab initio calculated energies and charge distribution are in good agreement with differences observed in the tetrazole-azide equilibrium constants. Copyright (C) 1999 John Wiley & Sons, Ltd.

  1,2,3,4-四唑的双重反应：锰催化的点击反应和脱氮环化反应。

  摘要：

  据报道，使用基于锰卟啉的催化系统的一般催化方法可实现两种不同的反应（点击反应和脱氮环化反应），并提供两种不同类型的氮杂环，即1,5-二取代的1,2,3-三唑（具有吡啶基）和1,2,4-三唑并吡啶。机理研究表明，尽管点击反应可能是通过离子机理进行的，这与传统的点击反应不同，但脱氮环化反应可能是通过亲电子的茂金属中间体而不是金属金属中间体进行的。总体而言，此方法非常高效，与其他方法相比，具有许多优点。例如，2副产品产生气体。

  catalytic amount of Fe(TPP)Cl and Zn dust. The reaction precludes the traditional, more favored click reaction between an organic azide and alkynes, and instead proceeds by an unprecedented metalloradical activation. The method is anticipated to advance access to the construction of important basic nitrogen heterocycles, which will in turn enable discoveries of new drug candidates.

  通过催化量的Fe（TPP）Cl和Zn粉尘发现了1,2,3,4-四唑和炔烃的分子间脱氮环化的独特概念。该反应排除了有机叠氮化物和炔烃之间传统的，更受欢迎的点击反应，而是通过空前的金属-金属活化来进行。预计该方法将促进重要的基本氮杂环的构建，而这反过来又可以发现新的候选药物。
