  • 作为反应物:
    描述:
    二乙基哒嗪-4,5-二羧酸酯 作用下, 以 甲醇 为溶剂, 反应 96.0h, 生成 Pyridazin-4,5-dicarbonsaeure-diamid

    名称:
    A ‘push–pull’ tropylium-fused aminoporphyrazine
    摘要:
    Crossover Linstead macrocyclization of cycloheptatrienylmaleonitrile and (dimethylamino)-maleonitrile gave access to an unsymmetrical (A(3)B) porphyrazine bearing six peripheral amino substituents and a fused cycloheptatrienyl ring. Subsequent hydride abstraction gave a tropylium-fused aminoporphyrazine, which contains both strongly electron-donating and withdrawing groups and thus can be labelled as a 'push-pull' macrocycle. Detailed structural studies of this novel porphyrazine are described. (C) 2009 Elsevier Ltd. All rights reserved.

  • Steric and electronic effects on the <sup>1</sup> H hyperpolarisation of substituted pyridazines by signal amplification by reversible exchange
    作者:Peter J. Rayner、Michael J. Burns、Elizabeth J. Fear、Simon B. Duckett
    DOI:10.1002/mrc.5152
    日期:2021.12
    rapid and cost-effective hyperpolarisation of substituted pyridazines. The 33 substrates investigated cover a range of steric and electronic properties and their capacity to perform highly effective SABRE is assessed. We find the method to be tolerant to a broad range of electron donating and withdrawing groups; however, good sensitivity is evident when steric bulk is added to the 3- and 6-positions of
    哒嗪基序作为药物和农用化学品的用途越来越受欢迎。因此,此类材料的检测和结构表征对于新产品的成功开发至关重要。可逆交换信号放大(SABRE)提供了一种显着提高磁共振方法灵敏度的途径,我们将其应用于取代哒嗪的快速且经济有效的超极化。研究的 33 种基材涵盖了一系列空间和电子特性,并评估了它们执行高效 SABRE 的能力。我们发现该方法能够耐受广泛的给电子基团和吸电子基团;然而,当空间体积添加到哒嗪环的 3 位和 6 位时,明显具有良好的灵敏度。我们通过参考二取代酯来优化该方法,该二取代酯在 9.4 T 下产生 > 9000 倍的信号增益(> 28% 自旋极化)。
