    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)。

    This paper describes the unequivocal synthesis of three new heterocycles: 2, 3, 6-triazaphenothiazine (7) and 2, 3, 6, 9-tetraazaphenothiazine (18), both parents of the respective ring systems and the 6, 8-dihydro-7, 9-di-oxo derivative of 2, 3, 6, 8-tetrahydrophenothiazine (12). These compounds were obtained by base-catalysed condensation of 4, 5-dichloropyridazine (8) with the appropriate o-amino-heterocyclic
