[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
2-(2-Pyridyl)benzimidazole (78.1 mg, 0.4 mmol) was dissolved in 10 mL of dry THF under N2 and this solution was transferred via cannula to suspension of sodium hydride (17.6 mg, 0.44 mmol, 60% in mineral oil) in dry THF. Reaction mixture was stirred at RT for 1 h and then chloro[l,3-bis(2,6-di-i-propylphenyl)imidazol-2- ylidene]copper(I) (195.1 mg, 0.4 mmol) was added. Reaction mixture was stirred at RT for 3 h. The resulting mixture was filtered through Celite and solvent was removed by rotary evaporation. Recrystallization by vapor diffusion of Et20 into a CH2C12 solution of product gave 154 mg (59.5%>) of dark yellow crystals. Anal, calcd. for C39H44CuN5: C, 72.47; H, 6.86; N, 10.48; Found: C, 72.55; H, 6.94; N, 10.84.
578743-87-0 is used more and more widely, we look forward to future research findings about [1,3-Bis(2,6-diisopropylphenyl)imidazol-2-ylidene]copper chloride
