Applications

Nickel(II) chloride is a mild Lewis acid used for the regioselective isomerization of dienols and selective reduction of alkenes to alkanes in presence of Lithium aluminum hydride. It is used as a precursor to nickel boride, finely divided nickel. It acts as a catalyst to prepare dialkyl arylphosphonates from phosphites and aryl iodide. It finds application in the electroplating of nickel onto other metal items. It is also used in the synthesis of semiconducting metal-containing polymers.

Notes

Hygroscopic. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with peroxides.
