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

Abstract

The oxidation of olefins and hydrazones of carbonyl compounds has been performed by using in situ anodically generated milder oxidant Mn(III) acetate at Pt electrode in acetic acid. The oxidation of acyclic olefins leads to the formation of 1,2-diacetate while in the case of cyclic olefin it results in the formation of γ-lactone ring onto double bond. Further, intermolecular 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 hydrazones of carbonyl compounds leads to its fragmentation products.
