The Uses of 1,3-BIS(2,4,6-TRIMETHYLPHENYL)-IMIDAZOLIDINIUM-CHLORIDE
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
General Description
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.
