Aerobic oxidation has been catching more and more attention because of its atom economy and environmental friendliness. Oxidation of diols is a challenge due to various oxidative products. Thus, highly selective aerobic oxidation affording specific products is of current interest. In this work, a combination of Fe(NO3)3·9H2O/TEMPO/KCl catalysis has been identified as an efficient recipe for the aerobic
