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.제조 방법
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.화학 반응
