Description

1,3-Bis-(2,6-Diisopropylphenyl)-Imidazolium Tetrafluoroborate is a high-purity, advanced N-heterocyclic carbene (NHC) precursor salt, essential for modern organometallic catalysis. This compound matters as a key ligand source for generating highly active and selective catalysts used in demanding chemical transformations. It is primarily needed by researchers and manufacturers in the pharmaceutical, fine chemical, and advanced materials sectors for applications such as cross-coupling, olefin metathesis, and polymerization reactions.

Application

• Precursor for generating N-heterocyclic carbene (NHC) ligands in organometallic catalysis.
• Key component in the synthesis of palladium, nickel, and gold catalysts for cross-coupling reactions (e.g., Suzuki, Heck, Buchwald-Hartwig).
• Ligand source for ruthenium-based catalysts used in olefin metathesis and ring-opening metathesis polymerization (ROMP).
• Research and development of novel catalytic systems for asymmetric synthesis in pharmaceutical intermediates.
• Production of specialized catalysts for polymerization processes and materials science.
• Use in academic and industrial R&D for exploring new reaction methodologies.
