[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
Chloro[l ,3-bis(2,6-di-i-propylphenyl)imidazol-2-ylidene]copper(I) (121.9 mg, 0.25 mmol) and silver triflate (64.2 mg, 0.25 mmol) were mixed under nitrogen in 25 mL flask and 10 mL of dry THF were added. Reaction mixture was stirred at RT for 30 minutes. Solution of 1 , 10-phenanthroline (45.05 mg, 0.25 mmol) in dry THF (5 mL) was added. Reaction mixture turned yellow and was stirred at RT overnight. Resulting mixture was filtered through Celite and solvent was evaporated on rotovap. Recrystallization from CH2Ch by vapor diffusion of Et20 gave 120 mg (61.4%) of yellow crystals. Anal, calcd. for C40H44CUF3N4O3S: C, 61.48; H, 5.68; N, 7.17; Found: C, 61.06; H, 5.61; N, 7.14. Structure was confirmed by IH-NMR spectrum of [(IPR)Cu(phen)]OTf (CDCb, 400MHz).
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
