Description générale

1,3-Bis(2,4,6-trimethylphenyl)imidazolinium chloride is an NHC (N-heterocyclic carbene) ligand which can bind with metal pre-catalysts to form complexes that show high catalytic activity.

Application

N-Heterocyclic Carbene Ligands

Precursor to an N-heterocyclic carbene catalysts used for:
  • A regioselective cycloadditon of terminal acetylenes with azides leading to 1,4-disubstitutedtriazoles. Internal acetylenes can also be used with this catalyst.
  • Markovnikov-type hydration of terminal alkynes
  • Hydrosilylation of ketones and cycloaddition of azides and alkynes
  • Suzuki-Miyaura reactions
  • Luminescence experiments

A new class of luminescent mononuclear and dinuclear N-heterocyclic carbene-containing gold(III) complexes has been synthesized and characterized. The X-ray crystal structures of most of the complexes have also been determined. Electrochemical studies reveal a ligand-centered reduction originated from the RC--N--CR

A versatile and highly efficient catalyst for the Huisgen cycloaddition reaction has been developed. Previously isolated or in situ generated azides yielded 1,2,3-triazoles with differently substituted alkynes in the presence of a [(NHC)CuBr] complex (NHC = N-heterocyclic carbene). Extremely high

The preparation of three series of [(NHC)CuX] complexes (NHC = N-heterocyclic carbene, X = Cl, Br, or I) is reported. These syntheses are high yielding and only use readily available starting materials. The prepared complexes were spectroscopically and structurally characterized.
