A highly selective radical dioxygenation of alkenes using hydroxamic acid and O2 was developed, and copper/cobalt was used as the catalyst without assistance of any additional ligands or bases. Mechanistic investigation disclosed that copper salt and O2 work in concert to activate hydroxamic acid, with Cu(I) and Cu(II) concurrently existing in this reaction.
开发了使用异羟肟酸和O 2对烯烃进行高度选择性的自由基双加氧反应,并且在没有任何其他配体或碱协助的情况下,将铜/钴用作催化剂。机理研究表明,铜盐和O 2协同作用以激活异羟肟酸,该反应中同时存在Cu(I)和Cu(II)。
