Abstract
An improved protocol for the oxidation of sec. alcohols by copper permanganate is described by carrying out the reaction in a homogeneous medium (acetic acid), affording rapid and complete conversion to the ketones.
Notes
Carus Chemical Co., La Salle, Illinois 61301.
The reverse work-up sequence, i.e. prior addition of bisulfate, was disadvantageous.
On standing in air, the precipitate (probably copper manganate) rapidly oxidized to the dark green cupric salt.
The inverse mode of addition (oxidant added to the alcohol) was experimentally inconvenient and offered no advantage.
