NICKEL IODIDE Chemical Properties,Usage,Production

Chemical Properties

Black, crystalline powder or blue-green crystals; hygroscopic.Soluble in alcohol and water.

Uses

Strongly accelerates Sml2 mediated homocoupling of imines into vicinal diamines and heterocoupling reactions between imines and ketones.1

Uses

Nickel Diiodide is used in preparation of Nickel complexes for migratory reductive cross-coupling.

Uses

Strongly accelerates Sml₂ mediated homocoupling of imines into vicinal diamines and heterocoupling reactions between imines and ketones.

Preparation

Nickel iodide can be prepared by dehydration of the hexahydrate or by the metathetic reaction between sodium iodide and nickel(II) chloride or nitrate in ethanol. It has the CdCl2 type lattice and is paramagnetic down to 75°K. Only one hydrate is well characterized—the blue-green NiI2?6H20 ; unlike the other halide hexahydrates, this contains [Ni(H2O)6]2+ cations.

Hazard

Toxic by ingestion.
