  • On the tautomerism of pyrazolones: the geminal 2J[pyrazole C-4,H-3(5)] spin coupling constant as a diagnostic tool
    作者:Wolfgang Holzer、Constanze Kautsch、Christian Laggner、Rosa M. Claramunt、Marta Pérez-Torralba、Ibon Alkorta、José Elguero
    DOI:10.1016/j.tet.2004.06.039
    日期:2004.8
    NOE effects the magnitude of the geminal 2J[pyrazole C-4,H3(5)] spin coupling constant permits the unambiguous differentiation between 1H-pyrazol-5-ol (OH) and 1,2-dihydro-3H-pyrazol-3-one (NH) forms. Whereas 1H-pyrazol-5-ols and 2,4-dihydro-3H-pyrazol-3-ones (CH-form) exhibit 2J values of approximately 9–11 Hz, in 1,2-dihydro-3H-pyrazol-3-ones this coupling constant is considerably reduced to 4–5 Hz
    已通过13 C-和1 H NMR光谱方法研究了在3(5)位未取代的吡唑啉酮的互变异构现象。除了化学位移方面的考虑和NOE影响外,双峰2 J [吡唑C-4,H3(5)]的自旋偶合常数还允许1 H-吡唑-5-醇(OH)和1,2-的明确区分。二氢-3 H-吡唑-3-酮(NH)形式。在1,2-二氢-3 H中,1 H-吡唑-5-醇和2,4-二氢-3 H-吡唑-3-酮(CH形式)的2 J值约为9–11 Hz。-吡唑-3-酮,该偶联常数显着降低至4-5 Hz。这主要归因于由于质子化或烷基化而除去了吡唑N -1中的吡咯N -1的孤对。根据获得的数据,2-取代的4-酰基-1,2-二氢-3 H-吡唑-3-酮主要以吡唑-5-醇的形式存在于CDCl 3或苯-d 6溶液中,而在DMSO- d中6少量的NH互变异构体也可能有助于互变异构体的组成。2,4-二氢-2-苯基-3 H-吡唑-3-酮(1-苯基-2-吡唑啉-5-酮)仅以CH形式存在于CDCl
