A useful and versatile procedure for benzylic oxidations with potassium permanganate/triethylamine has been developed. The methyl, methylene and methine groups are oxidized in good to excellent yields to benzylic aldehydes and ketones and to tertiary benzyl alcohols, respectively. This procedure can easily be carried out in conventional organic solvents without using any phase-transfer or supported catalysts.
