一般描述

4-氧代-TEMPO 是由2,2,6,6-四甲基-4-哌啶酮 (4-Oxo-TMP) 与1O2反应生成的。[1]它是 TiO2在水悬浮液中辐照时形成的稳定的顺磁性产物。[2]

应用

以 4-氧代-TEMPO 为氮氧化物标准品，用 ESR 波谱研究了 TiO2 在乙醇中光激反应生成单重态氧的过程。[1]它可作为自由基极化剂用于动态核极化 (DNP) 研究。[3]
自由基氮氧化物自旋探针通常用于：
  • 锂二次电池阳极氧化还原源的研究
  • 自由基生物学研究
  • 自由基自旋俘获
  • 电子顺磁共振研究
  • 聚合物化学和合成应用

TEMPO催化氧化

TEMPO（2,2,6,6-四甲基哌啶氧基或2,2,6,6-四甲基哌啶1-氧基）及其衍生物在有机氧化反应催化剂中可以作为稳定的硝酰基使用。TEMPO由Lebedev和Kazarnovskii于1960年发现，其具有的稳定自由基性质得益于其庞大的取代基团阻碍了自由基与其他分子之间发生反应。
