일반 설명Dilithium Tetrabromonickelate(II) is a source of soft nucleophilic bromide, reacting with epoxides[1] and functionalized aziridines[2] regiospecifically.
Preparative Method of Dilithium Tetrabromonickelate(II): anhydrous Lithium Bromide (6.96 g, 0.08 mol) and Nickel(II) Bromide (8.72 g, 0.04 mol) are stirred in dry THF (95 mL) at 25 °C. After 48 h, the stirring is stopped and undissolved solids are allowed to settle. The resulting clear dark blue solution is about 0.4M in Li2NiBr4. In reactions, 1.6 equiv of the reagent are typically added per equiv of substrate and allowed to stir at the requisite temperature until completion.[1,3]
