Abstract
[3264-82-2] C10H14NiO4 (MW 256.93) InChI = 1S/2C5H8O2.Ni/c2*1-4(6)3-5(2)7;/h2*3,6H,1-2H3;/q;;+2/p-2/b2*4-3-; InChIKey = BMGNSKKZFQMGDH-FDGPNNRMSA-L (catalyst for oligomerization, telomerization, hydrosilylation, hydrogenation, reduction, cross-coupling, oxidation, conjugate addition, addition to multiple bonds, and rearrangements1) Alternate Name: bis(acetylacetonato)nickel(II). Physical Data: pale green solid, mp 240 °C (dec); see also 2,4-Pentanedione. Solubility: sol ethers and aromatic and halogenated hydrocarbons. Analysis of Reagent Purity: atomic absorption is the method most commonly used. Preparative Methods: commercially available; can be prepared from Nickel(II) Chloride.1d Purification: recrystallize from benzene and sublime under vacuum (10−3 mmHg).1c Handling, Storage, and Precautions: nickel is now recognized as a cancer suspect agent as well as a possible teratogen and due precautions should be taken when handling the reagent. The anhydrous solid is stable, but is an irritant and hygroscopic and should preferably be stored in a sealed container to preclude contact with air and moisture. Solutions are more susceptible to atmospheric oxidation.
