Potassium iodide may be used as a catalyst in the following processes:

• Conversion of aromatic primary amines to the corresponding nitro compounds in the presence of tert-butyl hydroperoxide as oxidant.
• Conversion of aryl halide to aryl iodides in the presence of nickel catalysts.
• Preparation of sulfonated oxindoles from activated alkenes and sulfonylhydrazides in water and in the presence of 8-crown-6 and tert-butyl hydroperoxide.
