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
To anhydrous1,4-dioxane (20 mL), [Pd(acac)2] 1 g (3.3 mmol,1 equiv) and IPrHCl 1.56 g (3.7 mmol, 1.1 equiv) were added. The mixture was refluxed for 24 h. After reaction,solvent was evaporated under vacuum. Then, dichloromethane was added and stirred until no more soliddissolved. The solution was filtered and dichloromethane was removed under vacuum. Yellow powder obtained was washed with diethyl ether and dried under vacuum. Yellow solids, yield: 85%, 1H NMR (399.78 MHz, CDCl3 delta 7.49(t, 2H), 7.32 (m, 4H), 7.10 (s, 2H), 5.10 (s, 1H), 2.94 (td,4H), 1.81 (d, 6H), 132 (d, 12H), 1.08 (12H), 13C NMR(100.53 MHz, CDCl3) delta 186.70, 183.61, 155.98, 146.61,135.05, 130.42, 125.30, 124.20, 99.46, 28.54, 27.13,26.36, 23.07.
250285-32-6 is used more and more widely, we look forward to future research findings about 1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride
