Cyclopropyl derivative of 2,6-di-tert-butylphenol is synthesized as a probe to investigate the mechanism of base-catalyzed autooxidation of phenol derivatives. Our study indicates that one electron reduction of molecular oxygen from phenolate gives phenoxyl radical 3, a key intermediate of autooxidation. The coupling of phenoxyl radical and superoxide radical gives peroxylate anion 4 and produces the
合成了2,6-二叔丁基苯酚的环丙基衍生物作为探针,研究了碱催化的苯酚衍生物自氧化机理。我们的研究表明,电子从酚盐中还原分子氧会产生苯氧基3,这是自氧化的关键中间体。苯氧基自由基和超氧化物自由基的偶合得到过氧阴离子4并产生最终的环氧醇加合物6。
