NICKEL CHLORIDE LR
SKU: RXSOL-60-6605-088
Category: Lab Chemical-60
Nickel Chloride is a golden-yellow powder. It is used in electroplating and ink manufacturing. Nickel Chloride is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, DEP and EPA.
Densities and kinematic viscosities of molten mixtures of nickel(II) chloride in tetra-n-butylammonium iodide have been measured as functions of temperature and composition. The data on the kinematic viscosity have been analyzed using both Arrhenius and non-Arrhenius type equations.
NiCl2 and its hydrate are occasionally useful in organic synthesis
As a mild Lewis acid, e.g. for the regioselective isomerization of dienols :
- In combination with CrCl2 for the coupling of an aldehyde and a vinylic iodide to give allylic alcohols.
- For selective reductions in the presence of LiAlH4, e.g. for the conversion of alkenes to alkanes.
- As a precursor to Brown's P-1 and P-2 nickel boride catalyst through reaction with NaBH4.
- As a precursor to finely divided Ni by reduction with Zn, for the reduction of aldehydes, alkenes, and nitro aromatic compounds. This reagent also promotes homo-coupling reactions, that is 2RX → R-R where R = aryl, vinyl.
- As a catalyst for making dialkyl arylphosphonates from phosphites and aryl iodide.
