1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride, cas is 250285-32-6, it is a common heterocyclic compound, the chiral-catalyst compound, its synthesis route is as follows.,250285-32-6
taken the imidazole chlorine salt [(R 1 NCHCHNR 1) CH]Cl (0.42 g, 1.0 mmol), ferrous bromide (0.22 g, 1.0 mmol) and sodium bromide (0.33 g, 3.2 mmol), in thf as the solvent, the 60 C reaction under 16 hours. Centrifugal, supernatant fluid transfer, remove precipitation, is added to the supernatant liquid of the three ring hexyl phosphine (0.28 g, 1.0 mmol), in 30 C reaction under 6 hours. Vacuum to remove the solvent, hexane washing, drying, in a mixed solvent of toluene and tetrahydrofuran extraction, centrifugal supernatant fluid transfer, after concentrating the serum to obtain a target product, yield 85%.
With the rapid development of chemical substances, we look forward to future research findings about 1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride
