| 1,3-Bis(2,4,6-trimethylphenyl)imidazolium chloride Usage And Synthesis |
| Chemical Properties | off-white to beige powder | | Uses | 1,3-Bis(2,4,6-trimethylphenyl)imidazolium chloride is used as a phosphine-free ligand in various metal-catalyzed coupling reactions, often with advantageous results in difficult cases. For use in the Pd-catalyzed cross-coupling of aryl Grignards with aryl chlorides (Kumada reaction). Many examples have been recorded of the use of NHC ligands in the Suzuki coupling reaction, for examples utilizing 1,3-dimesitylimidazol-2-ylidene, in the coupling of arylboronic acids with relatively unreactive aryl chlorides. | | Reactions | Precursor to the nucleophilic carbene that serves as a bulky, electron-rich "phosphine mimic" for metal-catalyzed reactions.(a) Palladium-catalyzed Suzuki cross-coupling of aryl chlorides.(b) Palladium-catalyzed Kumada cross-coupling of aryl chlorides.(c) Ruthenium-carbene catalysts for ring-closing metathesis.(d) Suzuki coupling of aryltrimethylammonium salts.(e) Sonogashira coupling of aryl bromides.Precursor to a nucleophilic carbene that serves as catalyst.Ligand for arylation of aldehydes.Ligand for carbene catalyzed intermolecular arylation of C-H bonds.Catalyst for boron conjugate additions to cyclic and acyclic α,β-unsaturated carbonyls.Ligand for dehydrogenative cyclocondensation of aldehydes, alkynes, and dialkylsilanes.Precursor for carbene for conjugate silylation of alpha, beta-unsaturated carbonyls. |
