Abstract top

A new tetradentate chiral Schiff base ligand, C16H26N2O2, has been synthesized by the reaction of acetylacetone with (1R,2R)-(-)-1,2-diaminocyclohexane. Both of the molecules in the asymmetric unit are of the same chirality (R configuration), since the absolute configuration was determined by the starting reagent (1R,2R)-(-)-1,2-diaminocyclohexane. The six-membered cyclohexane ring is in a chair conformation, and the substituents are equatorial in the most stable conformation (trans-cyclohexyl). At the ring substituents, large conjugated -C=N-CH=C-OH systems exist, resulting from the original ketone converted into the enol form. With H atoms excluded, the atoms of each substituent lie in the same plane. The two molecules in the asymmetric unit have almost the same structure, with slight differences in the torsion angles between the substituents and the cyclohexane ring; the corresponding N1-(C-C-C)cyclohexane torsion angles are -177.2 (3) and 179.3 (4)° in one molecule and -176.5 (3) and 178.4 (4)° in the other. Two intramolecular O-H...N hydrogen bonds exist in each molecule.

Comment top

In recent years, research on Schiff bases has intensified because some of them form materials with non-linear optical (NLO) activity (Alemi & Shaabani, 2000) and because some can be used for the asymmetric oxidation of methyl phenyl sulfides (Sasaki et al., 1991). The search for new chiral ligands for asymmetric synthesis is an important task in organic chemistry. Various chiral Schiff bases are widely used in asymmetric reactions (Jiang et al., 1995; Belokon et al., 1997; Bandini et al., 1999, 2000; Kureshy et al., 2001; Cozzi, 2003). Herein, we report the synthesis and crystal structure of a new chiral Schiff base ligand (2Z,2'Z,4E,4'E)-4,4'-(cyclohexane-1,2-diylbis(azan-1-yl-1-ylidene))dipent-2-en-2-ol (Fig. 1).

The two molecules in the asymmetric unit have almost the same structure, with slight differences in the torsion angles between the substituents and the cyclohexane ring; the N—C3—C9—C19 and N3—C3—C10—C17 torsion angles are -177.2 (3) and 179.3 (4)°, respectively, and the N2—C1—C5—C23 and N2—C1—C7—C18 torsion angels are -176.5 (3) and 178.4 (4)Å, respectively.

Experimental top

Acetylacetone (2.4 g, 0.024 mol) in 6 ml of chloroform was added dropwise to a solution of chloroform (20 ml) containing (1R, 2R)-(–)-1,2-Diaminocyclohexane (1.14 g, 0.01 mol), which was kept at 0–5°C with vigorous stirring during the reaction. After complete addition which took approximately 30 min, the mixture was stirred for another 1 h at room temperature. After the evaporation of the solvent under reduced pressure, the crude product was recrystallized by slowly evaporating with petroleum ether to yield pale-yellow crystals.

Refinement top

Hydroxy and methyl H atoms were placed in calculated positions with O—H = 0.82 and C—H = 0.96 Å, and torsion angles were refined. Other H atoms were placed in calculated positions with C—H = 0.93 to 0.98 Å. In the absence of significant anomalous scattering effects, Friedel pairs were averaged.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
