[1,3-Bis(2,6-diisopropylphenyl)imidazol-2-ylidene]copper chloride, cas is 578743-87-0, it is a common heterocyclic compound, the copper-catalyst compound, its synthesis route is as follows.,578743-87-0
Carbazole (83.6mg, 0.5mmol) and NaH (12 mg, 0.5 mmol) was mixed with THF and 15 ml, atroom temperature under a nitrogen atmosphere until bubbling ceased (15 min) and stirred.Chloro [1,3-bis (2,6-diisopropylphenyl) imidazol-2-ylidene] was added copper (I) ((IPr) CuCl)(243.8mg, 0.5mmol), the reaction mixture was stirred for one hour did. Then, the mixture wasfiltered through a plug of Celite (registered trademark) under an inert atmosphere, and thesolvent was removed by rotary evaporation. The product was obtained as a white solid (170mg,55%).
As the rapid development of chemical substances, we look forward to future research findings about 578743-87-0
