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.
Preparation
In a flask, the imine(3 g, 10 mmol) was dissolved in tetrahydrofuran(25 ml), followed by dropwise addition of chloromethyl ethyl ether(1.04 g, 11 mmol). the mixture was stirred under N2 at 40 °C for 18 h, and then ethyl ether(25 ml) was added to separate white solid. The solid was filtered and washed with ethyl ether. Finally, the white solid was dried under vacuum affording 1,3-Bis(2,4,6-trimethylphenyl)imidazolium chloride.
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.
