As a common heterocyclic compound, it belongs to chiral-catalyst compound, name is 1,3-Dimesityl-4,5-dihydro-1H-imidazol-3-ium chloride, and cas is 173035-10-4, its synthesis route is as follows.
General procedure: [HIPr]2[PdCl4]: 0.45 g (1.0 mmol) of [HIPr]Cl was added to thesolution of 0.14 g (0.48 mmol) PdCl2(cod) in hot CH3CN (5 mL). Themixture was heated for 15 min, until the yellow solution becamered. The solution was cooled to room temperature and solventwas removed under reduced pressure. The product was precip-itated by addition of diethyl ether (2-3 mL). Product yield: 85%;elemental analysis calcd. (%) for PdCl4C54H78N4: C 62.88, H 7.62,N 5.46; found: C 62.37, H 7.46, N 5.40.1H NMR(500 MHz, CD3CN,25C, TMS): = 8.49 (s, 2H, N CH N); 7.57 (t, J(H,H) = 7.8 Hz, 4H,Ar); 7.42 (d, J(H,H) = 7.8 Hz, 8H, Ar); 4.48 (s, 8H, CH2CH2); 3.10(m, J(H,H) = 6.9 Hz, 8H, CH); 1.40 (d, J(H,H) = 6.9 Hz, 24H, CH3); 1.26(d, J(H,H) = 6.9 Hz, 24H, CH3,);13C NMR (125.75 MHz, CD3CN, 25C,TMS): = 160.0 (N CH N); 147.2 (Ar); 131.0 (Ar); 125.5 (Ar); 53.7(CH2CH2); 28.5 (CH); 24.0 (CH3); 23.5 (CH3).
