Oxidation of olefins and hydrazones by anodically in situ generated manganese (III) acetate

The oxidation of olefins and hydrazones of carbonyl compounds has been perf ormed by using in situ anodically generated milder oxidant Mn(III) acetate at Pt electrode in acetic acid. The oxidation of acyclic olefins leads to t he formation of 1,2-diacetate while in the case of cyclic olefin it results in the formation of gamma-lactone ring onto double bond. Further, intermol ecular carbolactonization of olefins has been achieved using more reactive carboxylic acid substrate i.e. ethyl hydrogen malonate at room temperature under the similar reaction conditions. Mn(III) acetate oxidation of hydrazo nes of carbonyl compounds leads to its fragmentation products.
