Synthesis of 4-iodo-2,6-diisopropylaniline [4, 5] . In a round bottom flask 2,6-di-iso-propylaniline (20 mL, 106 mmol, 1.0 equiv) and sodium bicarbonate (26.8 g, 219 mmol, 3.0 equiv) were introduced in MeOH (400 mL). Iodine (29.6 g, 116.5 mmol, 1.1 equiv) in CH2Cl2 (200 mL) was added and the mixture was stirred at room temperature for 12 h. Then, solids were filtered off and rinsed with CH2Cl2. The filtrate was concentrated under vacuum leading to a dark orange oil. A saturated solution of sodium thiosulfate was added to this oil and stirred for 2 h. After an extraction with CH2Cl2, the combined organic layers were dried over MgSO4 and concentrated under vacuum. The pure product was obtained as brown oil (23.5 g, 73% yield).
Synthesis of the title compound [6]. A mixture of (4-(methoxycarbonyl)phenyl)boronic acid (15.1 g, 84.17 mmol, 1.1 equiv), 4-iodo-2,6-diisopropylaniline (23.2 g, 76.52 mmol, 1.0 equiv), palladium tetrakis(triphenylphosphine) (1.77 g, 1.53 mmol, 2 mol%), and potassium carbonate (34.8 g, 253 mmol, 3.3 equiv) in 360 mL of dioxane/H2O (3/1) was stirred under nitrogen for 72 h at 90 °C. After the mixture was cooled to room temperature, it was extracted with CH2Cl2 and washed with H2O. The organic layer was dried with MgSO4, and the solvent was removed. The resulting crude product was purified by column chromatography using silica gel and petroleum ether/ethyl acetate (20/1) as the eluent. The product was obtained (18.08 g, 58.0% yield). Cystals were obtained by slow evaporation of an ethanol solution at room temperature over a period of seven days, yield: 0.58 g (92.5%). M.p.: 103–104 °C. Elemental analysis – found: C, 77.18%; H, 8.03%; N, 4.53%; calculated for C20H25NO2: C, 77.14%; H, 8.09%; N, 4.50%.
Experimental details
Hydrogen atoms were placed in geometrically idealized positions and refined using a riding model.
Comment
N-Heterocyclic carbenes (NHCs) are an important class of compounds that has found application in various fields of chemistry [7]. Several methods have been reported for the synthesis of NHCs since their discovery in the early 1990s [8]. Amines/anilines have emerged as versatile and useful building blocks in a variety of synthetic transformations, which can be generally designed as different NHCs [9].
The title compound consists of two substituted phenyl moieties. The dihedral angle between the planes of two aromatic rings is 38.7°. The bond lengths of C12–N1 and C1–O1 are 1.398(2) Å and 1.203(2) Å, respectively. And the bond lengths of C1–O2 and C2–O2 are 1.338(2) Å and 1.439(2) Å, respectively. As a result of the partial conjugation of the aromatic rings, the bond length of C6–C9 is 1.481(2) Å. The bond angle (C1–O2–C2) and (O1–C1–O2) are 116.90(17)° and 123.32(17)°, respectively. In the crystal packing, dipole-dipole and van der Waals interactions are effective besides hydrogen bonding. Bond lengths and bond angles within the molecular system are in agreement with the values reported [10].
