Application

Nickel(II) Chloride Hydrate serves as a versatile catalyst in various chemical processes, particularly in electroplating and organic reactions. It plays a significant role in the chemo-selective thioacetalization of aldehydes and, when combined with lithium aluminum hydride, functions as an efficient reducing agent for alkenes, alkynes, and organic halides, while also effectively cleaving N-O bonds and opening epoxides. Furthermore, this compound acts as a precursor in forming nickel-phosphine complexes, such as bis(triphenylphosphine)nickel(II) chloride, which are pivotal in facilitating reactions like alkyne trimerizations, carbonylations, and Suzuki-Miyaura cross-coupling, offering an alternative to palladium-based catalysts. Additionally, it is integral to the synthesis of the acetylacetonate complex of nickel, which is essential for producing the 1,5-cyclooctadiene complex used in organonickel chemistry. Nickel(II) Chloride Hydrate can also be utilized in forming the sandwich compound nickelocene through its dimethoxyethane complex, thereby further enhancing its applications in catalysis.
