, pyridine-2-carboxaldehyde oxime, acetophenone oxime, or dimethylglyoxime with diaryliodonium salts under mild reaction conditions and short reaction time in the presence of potassiumtert-butoxide is reported. The diaryliodonium counterion salt plays an important role in the reaction when it is carried out at 40 °C or lower temperatures. A metal-free method for the direct O-arylation of N-hydroxyphthalimide
