Lewis acid-activated oxidation of alcohols by permanganate.
The oxidation of alcohols by KMnO(4) is greatly accelerated by various Lewis acids. Notably the rate is increased by 4 orders of magnitude in the presence of Ca(2+). The mechanisms of the oxidation of CH(3)OH and PhCH(OH)CH(3) by MnO(4)(-) and BF(3)·MnO(4)(-) have also been studied computationally by the DFT method.
متن کاملThe Kinetics of the Oxidation of Acetaldehyde by Acid Permanganate
The kinetics of the oxidation of aceltaldehyde by acid permanganate has been studied. The reaction is of first order with respect to the aldehyde, the oxidant and hydrogen ion individually. The oxidation does not induce polymerisation of acrylonitrile and show a kinetic isotope effect (&H/AD = 6.1). The activation parameters for the oxidation and enolisation reactions have been evaluated. The r...
متن کاملPermanganate Oxidation mechanisms of Alkylarenes
Permanganate oxidation of benzaldehyde and p-nitrobenzaldehyde goes by two paths, i.e. a major one which is responsible for the normal oxidation giving good second order kinetic and minor path which involves a very small percent of a radical species formed by hydrogen atom abstraction by the permanganate ion. A mechanism involving Hydrogen atom abstraction by permanganate from the alkoxide ion ...
متن کاملKinetics and Mechanism of Oxidation of Phenyl Acetic Acid and Dl-mandelic Acid by Permanganate in Acid Medium
Kinetics of oxidation of phenyl acetic acid and DLMandelic acid by potassium permanganate in aqueous acetic acid and perchloric acid mixture reveals that the kinetic orders are first order in oxidant, first order in H+ and zero order in substrate for phenyl acetic acid. DL-Mandelic acid exhibits first order in oxidant and zero order in substrate. The results are rationalised by a mechanism invo...
متن کاملDielectric Properties of 1-Hexanol in Mesitylene Solution on Admixture of Aromatic Dihydric Alcohols
Broadband dielectric relaxation spectra (at 20 to 40 °C) are reported for three liquid alcohol/non polar solvent systems: Binary hexanol/mesitylene mixtures and two corresponding ternary mixtures, where 5 percent of hexanol are replaced by a dihydric alcohol, namely resorcinol (1,3-dihydroxyben zene) or 2,2'-dihydroxydiphenyl. The concentration of the polar substance(s) ranges from dilute sol...
