森北出版「化学辞典（第2版） | | 化学的特性 | Black, crystalline powder or blue-green
crystals; hygroscopic.Soluble in alcohol and water. | | 使用 | Nickel Diiodide is used in preparation of Nickel complexes for migratory reductive cross-coupling. | | 使用 | Strongly accelerates Sml2 mediated homocoupling of imines into vicinal diamines and heterocoupling reactions between imines and ketones.1 | | 使用 | Strongly accelerates Sml2 mediated homocoupling of imines into vicinal diamines and heterocoupling reactions between imines and ketones. | | 製造方法 | 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. | | 危険性 | Toxic by ingestion. |
