Descripción

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.

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
