Abstract

<span style="font-size:12.0pt;font-family: " times="" new="" roman";mso-fareast-font-family:"times="" roman";mso-ansi-language:="" en-in;mso-fareast-language:en-in;mso-bidi-language:ar-sa"="" lang="EN-IN">The oxidation of olefins and hydrazones of carbonyl compounds has been performed by using <i>in situ </i>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 <img src='/image/spc_char/gamma2.gif' border=0>-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.</span>
