Descrição

Descrição geral

Potassium iodide is a water soluble inorganic salt that can be prepared by reacting hydrogen iodide and potassium bicarbonate.

Aplicação

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.
