| Hazard Information | Back Directory | [Uses]
Catalyst for the regioselective preparation of magnetic resonance contrast agents1Reagent for: • ;Regioselective synthesis of (-)-gallocatechin2• ;Synthesis of ATP mimics3• ;Reaction with unsaturated epoxides4 | [Preparation]
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] | [General Description]
Dilithium Tetrabromonickelate(II) is a source of soft nucleophilic bromide, reacting with epoxides[1] and functionalized aziridines[2] regiospecifically. | [reaction suitability]
core: nickel
reagent type: catalyst | [storage]
Dilithium Tetrabromonickelate(II) should be generated in a dry, inert atmosphere and used
directly.
