Source of material
A solution of 2-ethylphenol (2.4 g, 20 mmol), MgCl2 (5.7 g, 60 mmol), paraformaldehyde (9.0 g, 0.1 mol), triethylamine (15 g 149 mmol) in acetonitrile (50 mL) was refluxed until full consumption of 2-ethylphenol (as indicated by TLC). The mixture was quenched with HCl (1 M) and extracted with ethyl acetate. The combined organic layers were washed with brine, dried with MgSO4 and evaporated under reduced pressure. The crude residue was purified by column chromatography to obtain 3-ethyl-2-hydroxybenzaldehyde (2.2 g, 73% yield) as a yellow oil.
Synthesis of the title compound [5]: 3-ethyl-2- hydroxybenzaldehyde (1 g, 6.7 mmol) was dissolved in 30 mL of ethanol and (1R, 2R)-(−)-1,2-diphenylethane-1,2-diamine (0.71 g, 3.35 mmol) was added to the solution. The solution was heated to reflux for 4 h. The solvent was removed in vacuo and 1.48 g of the product was obtained as yellow solid (95% yield). Crystals were obtained by slow evaporation of an ethanol solution at room temperature over a period of seven days, yield: 0.72 g (93%). M.p.: 105–107 °C. Elemental analysis – found: C, 80.68%; H, 6.72%; N, 5.84%; calculated for C32H32N2O2: C, 80.64%; H, 6.77%; N, 5.88%.
Experimental details
Data were collected via CrysAlisPRO 1.171.39.7e [1], the structure of crystal was determined by SHELXT [2] and refined by OLEX2 [4] and SHELXL [3].
The absolute structure determination succeeded as the derived Flack parameter is found to be near zero with a low standard uncertainty [−0.02(9) from 2090 selected quotients] using Parsons’ method [6]. There is a small disorder of one ethyl group (C22, C23) which was not included in the refinement.
Comment
Hugo Schiff described the condensation between an aldehyde and an amine leading to a Schiff base in 1864 [7]. Schiff base ligands are privileged ligands, as they are easily prepared by the condensation between aldehydes and imines. Stereogenic centres can be introduced in the synthetic design. Schiff base ligands are able to coordinate many different metals, and to stabilize them in various oxidation states, enabling the use of Schiff base metal complexes for a large variety of useful catalytic transformations [8], [9], [10]. When two equivalents of salicylaldehyde are combined with a diamine, a particular chelating Schiff base is obtained – known as salen – with four coordinating sites and two axial sites open to ancillary ligands. Here, we report a new chiral salen compound.
The asymmetric unit of the title structure contains one 6,6′-((1E, 1′E)-(((1R, 2R)-1,2-diphenylethane-1,2-diyl) bis(azanylylidene))bis(methanylylidene))bis(2-ethylphenol). In the crystal structure, bond lengths and bond angles within the molecule are in agreement with the values reported [11]. The bond lengths of C15–N1 and C24–N2 are 1.278(3) and 1.275(3) Å, respectively. As a result of the conjugation of the benzene moiety and adjacent carbon-nitrogen double bond, the bond lengths of C15–C16 and C24–C25 are 1.457(4) and 1.461(4) Å respectively, which is shorter than that of typical C–C bond. Furthermore, the bond lengths of C17–O1 and C30–O2 are 1.351(3) and 1.358(3) Å, respectively. The bond angles (C15–N1–C7) and (C24–N2–C8) are 117.5(2)° and 118.8(2)°, respectively. There are two intramolecular hydrogen bonds (d D···A 2.63 Å; H···A 1.904 Å) between H1 and N1 atom and (d D···A 2.594 Å; H···A 1.864 Å) between H2 and N2 atom, which stabilize the crystal structure [11], [12]. In the crystal packing, dipole-dipole and van der Waals interactions are effective besides an intermolecular hydrogen bond in the molecular packing.
