26.1.1.2.5.5 Variation 5: With Periodate

DOI: 10.1055/sos-SD-026-00003

von Angerer, S.Science of Synthesis, (20052667.

Periodate is successfully applied in the oxidation of secondary alcohols to ketones after the original sodium cation has been replaced by a quaternary ammonium[‌198‌,‌199‌] or phosphonium[‌200‌,‌201‌] ion. Tetrabutylammonium periodate has been used as an oxidizing agent in the presence of a poly(4-vinylpyridine)-supported sodium ruthenate catalyst for the conversion of simple secondary alcohols into ketones.[‌202‌] An alternative catalyst for this reaction is rutheniumcopperaluminum hydrotalcite prepared from ruthenium(III) chloride, copper(II) chloride, and aluminum trichloride in water.[‌203‌]
