在这项研究中，活性钴基催化剂报道了1-癸烯作为非贵金属的无溶剂有氧环氧化反应，替代传统使用的金催化剂。不使用牺牲还原剂，在环境压力下使用空气作为主要氧化剂。考察了不同自由基引发剂和产物随时间分布的影响。证据的反应机制类似于先前报道的1-癸烯的金催化有氧环氧化，给出。此外，催化剂的稳定性受载体选择的影响。
In this study, active cobalt-based catalysts are reported for the solvent-free aerobic epoxidation of 1-decene as a non-noble metal, alternative to the conventionally used gold catalyst. No sacrificial reductant is applied and air is used as primary oxidant at ambient pressure. The influence of different radical initiators and the product distribution over time is investigated. Evidence for a reaction mechanism similar to the previously reported gold-catalysed aerobic epoxidation of 1-decene, is given. Furthermore, it is shown that the catalyst stability is influenced by the choice of the support.
