Bis(1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene)copper(I) tetrafluoroborate
Bis(1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene)copper(I) tetrafluoroborate (CAS 886061-48-9; C54H72BCuF4N4; molar mass 927.53 g/mol) is a well-defined cationic copper(I) N-heterocyclic carbene (NHC) complex bearing two bulky IPr ligands and a tetrafluoroborate counter-ion. Supplied as a high-melting solid (mp >300 degC), it serves as an efficient homogeneous precatalyst, notably for the hydrosilylation of carbonyl compounds. Tech Serve Solutions supplies it as a research-grade reagent for catalysis and synthetic chemistry.

Hydrosilylation of carbonyl compounds
Acts as an efficient copper(I) NHC precatalyst for the hydrosilylation of aldehydes and ketones, providing a defined, ligand-stabilised copper source for reduction chemistry.
Homogeneous copper catalysis
The two strongly donating IPr carbene ligands give a stable, electron-rich copper(I) centre, making the complex a useful building block in homogeneous catalyst development and method screening.
Organometallic and synthetic chemistry research
Used as a discrete, single-component precatalyst in organic synthesis and chemical methodology studies where a reproducible NHC-copper(I) species is required.
Reference NHC-copper complex
Serves as a structurally defined bis-NHC copper(I) tetrafluoroborate for academic and industrial laboratories investigating carbene ligand behaviour and copper coordination chemistry.
