  Oxidations of hydrocarbons, cycloalkanes and alkenes, arylalkanes, and a variety of other organic substrates are accomplished by cobalt-N-hydroxysuccinimide co-catalyzed reactions with dioxygen under unusually mild, near ambient conditions of temperature and pressure. The improved safety of the oxidation method and the high yields of product obtained make use of a unique combination of cobalt (II) complexes with N-hydroxysuccinimide. These autoxidation reactions do not have prolonged initiation times. Many of these reactions can be safely performed under normal chemical laboratory conditions and do not require specialized equipment or reagents.

  烃类、环烷烃、烯烃、芳基烷烃以及其他多种有机底物的氧化反应可以通过钴-N-羟基琥珀酰亚胺共催化反应与二氧化碳在异常温和、接近环境条件下的温度和压力下完成。氧化方法的改进安全性和获得的高产率产品利用了钴(II)络合物与N-羟基琥珀酰亚胺的独特组合。这些自氧化反应没有长时间的启动时间。许多这些反应可以在正常化学实验室条件下安全进行，不需要专门的设备或试剂。
