Cobalt(II)-Catalyzed Reaction of Enolizable Aldehydes with Alkenes in the Presence of Dioxygen: The Role of Acyl Radical

Article abstract of DOI:10.1021/jo00083a029

Complex cobalt(II) (1) catalyzes the reaction of enolizable aliphatic aldehydes and dioxygen with an electron-deficient alkene to afford the adducts 4 and 5, whereas the reaction with unactivated alkenes leads to the corresponding epoxides 6.These reactions are proposed to proceed via a common pathway involving acyl radicals.
