Oxidation by cobalt(III) acetate. Part 11. Oxidation of conjugated dienes by cobalt(III) acetate in acetic acid
Abstract
The oxidation of aliphatic and aromatic conjugated dienes by cobalt(III) acetate in acetic acid has been investigated. Open chain dienes were smoothly oxidized by cobalt(III) acetate to give vic-diol derivatives. Cyclo-octadiene was slowly converted into allylic acetate by the oxidant. The reaction mechanism is discussed in terms of a Co-co-ordinated radical cation.
