KMnO4 on activated fly ash (KMnO4-FY) was found to efficiently oxidize aliphatic, aromatic and hetero aromatic alcohols into their respective carbonyl compounds by a grinding method under solvent-free conditions. The reaction cleanly proceeded at room temperature to afford the products in good to ...
Chromic Acid, PCC, and KMnO4 Video 6 – Sodium Borohydride (NaBH4) Reduction You'll cover a variety of reactions involving the reduction of carbonyl compounds. NaBH4 is a weak reducing agent commonly seen reacting with ketones to form secondary alcohols and aldehydes to form primary alcohols. ...
Introduction The selective oxidation of C-H bonds has always been a challenging task. Typical of this is the oxidation of alcohols to aldehydes or ketones. Usually only the strongest oxidizing agents, such as KMnO4, Br2, MnO2, SeO2, RuO4, and acid dichromate can perform this reaction.1 Only...

Esters and/or acids and/or ketones are the major products of oxidation of primary and secondary alcohols with benzyl(trielhyl)ammonium permanganate, which can be safely handled below 50 °C. For primary alcohols the reagent is superior than solid carriers impregnated with KMnO4.doi:10.1002/anie....
The oxidation of alcohols to the corresponding carbonyl derivatives was studied over various primarily oxidants such as H2O2, MnO2, KMnO4 and K2Cr2O7 using catalytic amount of heteropoly acid, H3PW12O40 with or without solvent. The best reaction condition for this conversion was confirmed to be ...
Oxidation of the alcohols (I) or the diols (III) and (V) with solid KMnO4/CuSO4·5H 2 O in the presence or absence of a base yields the acids (II) or the lactones (IV) and (VI).doi:10.1002/chin.198843179JEFFORD, C. W.
The oxidation of organic compounds under ion exchange resin (IER) catalysis by KMnO4 has been studied in CH2Cl2 under reflux conditions. Secondary aliphatic and aromatic alcohols are converted to ketones, alkyl arenes and sulfides oxidized to corresponding ketones and sulfones, respectively, and thiols...
