Application

NiI2 has found some industrial applications as a catalyst in carbonylation reactions. It is also has niche uses as a reagent in organic synthesis, especially in conjunction with samarium(II) iodide.

Like many nickel complexes, those derived from hydrated nickel iodide have been used in cross coupling.
