    摘要:
    合成了六个取代的5-嘧啶醇,研究了它们与自由基反应的热化学和动力学,并将其与同等取代的酚进行了比较。为了评估其作为自由基的氢原子供体的潜力,我们使用自由基平衡电子顺磁共振技术测量了其OH键离解焓(BDE)。这表明,5-嘧啶醇中的OH BDE平均比同等取代的酚类中的高约2.5 kcal mol(-1)。结果与理论预测吻合良好,证实了取代基对5-嘧啶醇的OH BDE的影响与对苯酚中Obond; H BDE的影响基本相同。通过抑制AIBN引发的苯乙烯的自氧化,以及通过竞争动力学与烷基和烷氧基的反应,研究了这些化合物与过氧自由基的反应动力学。尽管它们的OH BDE较大,但5-嘧啶醇似乎将其酚氢原子转移到过氧自由基上的速度与同等取代的酚一样快,而它们对烷基自由基的反应性却远远超过了相应的酚。我们建议,这种速率的提高是由于这些原子的过渡态中的极性效应引起的,该速率的提高在烷基自由基反应的情况下较大,在

  • Novel chain-breaking antioxidants

    公开号:US20020143025A1
    公开(公告)日:2002-10-03
    Compounds, preferably 5-pyrimidinol and 3-pyridinol derivatives, that act as effective chain breaking antioxidants of both the lipid and water-soluble variety (analogous to the natural Vitamins E and C), many of which are more reactive toward peroxyl radicals than the most potent form of Vitamin E. These compounds may exhibit many chemopreventive effects associated with conditions in which free radical-mediated cellular damage or disruption is implicated and Vitamins E and C are shown to have protective effects. Additionally, these compounds should be excellent oxidation inhibitors as additives to fuels, lubricants, rubber, polymers, chemicals, solvents and foodstuffs.
    化合物,最好是5-嘧啶醇和3-吡啶醇衍生物,作为有效的链断裂抗氧化剂,既可以溶解于脂质又可以溶解于水(类似于天然维生素E和C),其中许多对过氧自由基的反应性比最有效的维生素E形式更高。这些化合物可能展现出许多与自由基介导的细胞损伤或破坏相关的化学预防效应,而维生素E和C已经显示出具有保护作用。此外,这些化合物应该作为添加剂,对燃料、润滑剂、橡胶、聚合物、化学品、溶剂和食品等具有出色的氧化抑制作用。
