Abstract
An universal catalytic system 4-acetamido-2,2,6,6-tetramethylpiperidine-1-oxyl/KI/pyridine base for the conversion of alcohols into carbonyl compounds and derivatives of carboxylic acids is developed. The use of pyridine, 2,6-lutidine or collidine made it possible to obtain carbonyl compounds (in yield up to 100%) after passing a charge of 2–2.2 F. In the presence of pyridine, aliphatic alcohols are converted to esters (in yield up to 35%) after passing 4 F. Acid anhydrides (in yield up to 80%) are formed using 2,6-lutidine or collidine after passing 5–6 F. Nitriles were obtained (in yield up to 99%) in the presence of 2,6‑lutidine and a source of nitrogen after passing 4–4.5 F.
