250285-32-6, 1,3-Bis(2,6-diisopropylphenyl)imidazolium chloride is a chiral-catalyst compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
In a glove box, a Schlenk flask equipped with a magnetic bar is loaded with the imidazolium salt IPr EtaC1 (2.96 g, 7 mmol), Pd(acac), (1.53 g, 5 mmol) and dry dioxane (100 mL). The flask was taken outside the glove box and placed in an oil bath at 100 C over a magnetic stirrer for 6 hours. After that time, the solution looked clear with no solid remaining. The solvent was evaporated in vacuo and diethyl ether was added until no more solid was dissolved. The solution is filtered and the solid washed with diethyl ether (2 x 10 mL). The solvent was evaporated in vacuo to yield 2.99 g (95 %) of the desired compound as a yellow powder.1H NMR (delta, 400 MHz, CDCl3): 7.51 (t, / = 7.8 Hz, 2H), 7.35 (d, / = 7.8 Hz, 4H), 7.12 (s, 2H), 5.12 (s, IH), 2.95 (q, / = 6.4 Hz, 4H), 1.84 (s, 3H), 1.82 (s, 3H), 1.34 (d, / = 6.4 Hz, 12H), 1.10 (d, / = 6.4 Hz, 12H).
