    氮阳离子进行化学氧化将α-生育酚(维生素E)及其相关色酚模型化合物转化为苯氧鎓离子
    摘要:
    构成维生素E的主要油类成分α-生育酚(α-TOH)及其非天然固体6-羟基-2,2,5,7,8-五甲基苯并二氢吡喃和6-羟基-2,5,7,8-四甲基-2-羧酸结构上相关的类似物与2摩尔当量NO的定量氧化+的SbF 6 -在CH 3 CN在233 K至形式phenoxonium阳离子(α-TO +的SbF 6 - )的化学可逆二电子/一质子过程。溶液相红外光谱法,1 H和1313 C NMR光谱学以及使用基于密度和基于波函数的模型对光谱数据进行相应的理论计算,可以证明非常稳定的苯氧鎓阳离子的身份。在羟基和苯甲酚环结构对位的氧原子似乎是稳定苯氧鎓离子的重要因素,这增加了有趣的可能性,即阳离子在维生素的作用方式中起关键作用生物系统中的E。尽管苯氧鎓阳离子对亲核试剂(例如水)具有反应性,但它​​们在疏水(亲脂)环境中可能是中等稳定的,在该环境中已知维生素E是天然存在的。
