Nickel dichloride hexahydrate

Dichlorobis(tricyclohexylphosphine)nickel is first prepared by the following procedure, which is a slight modification of the original synthesis of Turco, Scatturin, and Giacometti.7 A solution of tricyclohexylphosphine (14.0 g, 0.050 mol) in benzene (50 mL) and ethanol (300 mL) is added slowly to a solution of nickel dichloride hexahydrate (5.9 g, 0.025 mol) in ethanol (100 mL) at room temperature in a nitrogen or an argon atmosphere. A reddish, crystalline precipitate deposits immediately. After the addition is complete, the mixture is left for a few hours, then the product is filtered off, washed with ethanol, and dried in vacuo. (Yield 16.4 g 95%.)... 

To a solution of the azide (617 mg, 1.43 mmol) in methanol/THF (30 mL, 3 1) at 0 °C was added nickel dichloride hexahydrate (542 mg, 2.28 nunol) followed by sodium borohydride (248 mg, 6.57 mmol) over 10 min. After 30 min, the black mixture was allowed to warm to 25 °C, diluted with EtOAc (40 mL), and filtered through Celite. The solution was further diluted with EtOAc (50 mL) and washed with brine (2 x 25 mL) and 0.01 M EDTA solution (1 x 25 mL, pH 7.5, K-phosphate buffer). After solvent removal in vacuo, the resulting oil was purihed by silica gel chromatography (100% EtOAc then EtOAc methanol, 12 1) to give 569 mg (98%) of the amine.

Nickel forms yellow anhydrous halides NiXjlX = F. Cl. Br) and a black iodide Nil2 all these halides are made by direct combination of the elements, and the chloride by reaction of sulphur dichloride oxide with the hydrated salt. All dissolve in water to give green solutions from which the hydrates can be crystallised the solutions contain the ion [NifHjOls], and the chloride crystallises as NiCl2.6H2O, nickel(II) chloride hexahydrate.
