A green and very mild method for the oxidation of benzyl alcohols to aromatic aldehydes with excellent conversions has been developed. The reaction could be carried out directly in air at room temperature and was catalyzed by bis (8-quinolinolato) copper (Ⅱ) with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) as co-catalysts. The methodology provided a practical approach for the synthesis of aromatic aldehydes, which has the advantages of environment-friendly, simple workup and high yields.
Key words: benzyl alcohol, aromatic aldehyde, copper, TEMPO, aerobic oxidation
