Bis(2,4-pentanediono)nickel Usage And Synthesis

Physical Properties

Emerald-green crystals; orthorhombic structure; density 1.455 g/cm3 at 17°C; melts at 230°C; soluble in water, alcohol, chloroform, benzene and toluene; insoluble in ether.

Uses

Bis(2,4-pentanediono)nickel is used as a catalyst in hydrogenation and other organic reactions.

Preparation

Nickel acetylacetonate is prepared by the reaction of acetylacetone with nickel chloride hexahydrate or nickel hydroxide, followed by crystallization:
2CH3C(=O)CH2C(=O)CH3 + Ni(OH)2 → Ni(CH3C(=O)CHC(=O)CH3)2 + 2H2O

Chemical Properties

light green powder(s); hygroscopic; trimer; there is a hydrate, CAS RN 120156-44-7 [STR93] [ALD94] [COT88]

Uses

Catalyst for organic reactions.

Safety Profile

Confirmed human carcinogen. Poison by intraperitoneal route. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

Wash the green solid with H2O, dry it in a vacuum desiccator and recrystallise it from MeOH. [Charles & Pawlikowski J Phys Chem 62 440 1958.] The complex can be conveniently dehydrated by azeotropic distillation with toluene, and the crystals may be isolated by concentrating the toluene solution. [Wilkinson et al. J Am Chem Soc 76 1970 1954, Beilstein 1 IV 3677.]
