9,10-Dioxo-9,10-dihydroanthracene-1,4-diyl diacetate

J.-J. Zhang, C.-X. Yin and F.-J. Huo

Abstract top

In the title compound, C18H12O6, the anthraquinone ring system is nearly planar [maximum deviation = 0.161 (3) Å] and both acetate groups are located on the same side of the ring plane. A supramolecular architecture arises in the crystal owing to [pi]-[pi] stacking between parallel benzene rings of adjacent molecules [centroid-centroid distance = 3.883 (4) Å] and weak intermolecular C-H...O hydrogen bonding.

Comment top

The title compound has symmetry space structure and obvious color. It can be used to synthesize various dyes and are common structural subunits of many biologically active quinonoids (Mal et al., 2007). It also can be modified into synthetic dyes intermediates, 1,4-diamino anthraquinone. Its readily deprotection of acetate groups forms 1,4-dihydroxyanthraquinone (1,4-DHA), which can be induced to self-assembly to form a metallo-supramolecular coordination polymers under certain condition (Gianneschi et al., 2005; Thomas, 2007; Lee & Lin, 2008) and demonstrate good selectivity and binding for planar aromatic guests, small organic molecules and transitional metal ions, such as dichloromethane and iridium (Han et al., 2009; Lusby, 2012; Han et al., 2010)

The molecular conformation is illustrated in Fig. 1. In the title compound, C18H12O6, the anthraquinone ring system is nearly planar [the maximum deviation being 0.161 (3) Å], both acetate groups are located on the same side of the ring plane. A three-dimensional supramolecular architecture arises in the crystal owing to π-π stacking between centro-symmetrically related benzene rings [centroid-centroid distance 3.883 (4) Å] and weak intermolecular C—H···O hydrogen bondig.

Experimental top

To a stirred solution of 1,4-dihydrory-9,10-anthraquinone (4.6 g, 19.1 mmoL) in CH2Cl2 (50 ml), Ac2O (2 ml) and pyridine (one drop) were added. After the solution was stirred overnight at room temperature, it was evaporated under vacuum. The crude products were dissolved in water and then extracted with EtOAc. The combinded organic layer was washed with brine, and then dried with Na2SO4. The solvent was removed under the reduced pressure and the residue was purified by column chromatography using petroleum ether/ethyl acetate (v/v 2:1, Rf = 0.50) as an eluent to afford 9,10-dioxo-9,10-dihydroanthracene-1,4-diyl diacetate as a white solid. Colorless single crystals were obtained from the ethyl acetate solution.

Refinement top

All H atoms were initially lacated in a difference Fourier map. H atoms on Csp3 were treated as riding with C—H = 0.96 Å and Uiso(H) = 1.5Ueq(C) of the parent atom. The H atoms on Csp2 were treated as riding with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C).

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 > 2 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.
