Description

Nickel, [4,4′-Bis(1,1-Dimethylethyl)-2,2′-Bipyridine-κn1,κn1′]Dibromo-, (Sp-4-2)- is a high-purity, organometallic coordination complex featuring a nickel center with a sterically hindered, electron-rich di-tert-butyl bipyridine ligand. This compound matters for its role as a sophisticated catalyst precursor in advanced organic synthesis and materials science, offering precise control over stereochemistry and reaction pathways. It is primarily needed by research institutions and industrial R&D departments focused on developing novel pharmaceuticals, specialty polymers, and next-generation electronic materials.

Application

• Asymmetric Catalysis: Serves as a key precursor for chiral nickel catalysts in enantioselective C-C and C-X bond-forming reactions.
• Cross-Coupling Reactions: Used in Negishi, Suzuki-Miyaura, and related cross-coupling methodologies for constructing complex molecular architectures.
• Polymerization Catalyst: Employed in the controlled synthesis of specialty polymers and oligomers with specific tacticity.
• Organic Light-Emitting Diodes (OLEDs): Investigated as an electron transport or emissive layer component in OLED device fabrication.
• Academic & Pharmaceutical Research: A valuable tool for mechanistic studies and the development of new synthetic routes to active pharmaceutical ingredients (APIs).
• Ligand Transfer Agent: Acts as a source of the sterically demanding di-tert-butyl bipyridine ligand for metallation reactions.
