|Title:||Mn(VII) oxidation using cetyltrimethylammonium permanganate: Oxidation of alkyl cinnamates|
Mishra, Bijay K
|Abstract:||The kinetics and mechanism of Mn(VII) oxidation of substituted alkyl (E) cinnamates by cetyltrimethylammonium permanganate have been studied spectrophotometrically at 524 nm in chloroform medium. From the formation of aldehydes and Mn(III) a mechanism for the oxidation reaction has been proposed. The formation of cyclic manganate(V) diester intermediate is supported by a large negative entropy of activation. A negatively charged transition state is also supported by the Hammett plot.|
