Homogeneous Oxidation of Alcohols by Copper Permanganate

Aldehydes and ketones

“…23 Unlike most of the existing catalysts used to accomplish this type of reaction, the bistrifuoromethylsulfonamides of aluminium, titanium and ytterbium can be used in substoichiometric quantities. Fries reactions of phenol and 1-naphthol derivatives with acyl chlorides also proceed smoothly in the presence of a small amount of Sc(OTf), (5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20) Arenes are converted to their corresponding trifluoromethyl ketones by its action in the presence of aluminium chloride. The synthesis of a variety of ketones, in moderate yield, by the lithium-mediated coupling of carboxylic acids and alkyl or aromatic chlorides has been detailed by Yus and co-workers (Scheme 8a).…”

Chapter 8. Synthetic methods

“…The reaction is carried out in a homogeneous medium (acetic acid), affording rapid and complete conversion of the alcohols to ketones. 156 Chromium trioxide and tricapryl(methy1)ammonium chloride (Aliquot 336) also serves as an efficient system for the oxidation of alcoh01s.l~~ Hexadecyl silica-supported cupric nitrate, in carbon tetrachloride, oxidises alcohols to their corresponding carbonyl compounds. It oxidises primary alcohols in the presence of secondary alcohols with absolute chemoselectivity in high yields.15* The catalytic activity of cerium(rv) doped Weakley-type heteropolyoxometalates for the H 2 0 2 oxidation of primary and secondary alcohols has been evaluated for the first time.…”

Three Reagents In One: Ammonium Permanganate In The Oxidation Of Benzyl Alcohol

“…Benzyl alcohol and its ring-substituted derivaives can be easily oxidized by various permanga nates [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. Reaction conditions, such as the najure of the oxidant and the medium, temperature, lie.…”
