a catalyst in an ionicliquid solvent for the aerobic oxidation of alcohols by using NaNO2 and HCl as co‐catalysts. To this end, a TEMPO derivative bearing a quaternary ammonium group, [4‐Bu2MeN‐TEMPO][PF6] (1), was prepared. It was subsequently shown that this ionic TEMPO derivative is an efficient catalyst for the aerobic oxidation of a variety of primary and secondary alcohols. It exhibits a synergistic
