Abstract top

In the title compound, C31H28O4, the asymmetric unit contains two crystallographically independent molecules. In these two molecules, the four dihedral angles between each pair of phenyl rings on the same C atoms are 75.4 (1), 83.0 (1), 85.0 (1) and 80.4 (2)°. All of the nonplanar six-membered heterocycles adopt chair conformations. Intermolecular C-H...[pi] and weak C-H...O interactions link the molecules and are effective in the stabilization of the crystal structure.

Comment top

Owing to the characteristic axial and helical chirality, the stereochemistry of spiranes with six-membered rings has been extensively studied (Cismaş et al., 2005). In the past three decades, most of these investigations were carried out with spiranes containing 1,3-dioxane units (Mihiş et al., 2008; Sun et al., 2010). We herein present the structure of 3,3,9,9-tetraphenyl-2,4,8,10-tetraoxaspiro[5.5]undecane (I).

In the crystal structure of (I), the asymmetric unit contains two crystallographically independent molecules (Fig. 1). In these two molecules, the four dihedral angles between each two phenyl rings on the same C atoms are all different. In one molecule, the dihedral angles formed by the phenyl rings (C7–C12) and (C13–C18) are 75.4 (1)° and 83.0 (1)° for the phenyl rings (C20–C25) and (C26–C31). In the other molecule, the dihedral angles between the phenyl rings (C38–C43) and (C44–C49) are 85.0 (1)° and 80.4 (2)° for the phenyl rings (C51–C56) and (C57–C62). The four nonplanar six-membered heterocycles [(O1/O2/C1–C3/C6), (O3/O4/C2/C4/C5/C19), (O5/O6/C32–C34/C37) and (O7/O8/C33/C35/C36/C50)] all adopt chair conformations.

Intermolecular C—H···π and weak C—H···O interactions link the molecules and are effective in the stabilization of the crystal structure (Table 1).

Experimental top

To a solution of benzophenone (7.3 mmol, 1.33 g) and pentaerythritol (4 mmol, 0.54 g) in toluene (30 ml), phosphotungstic acid (30 mg) as catalyst was added, respectively. The mixtures were refluxed for 4 h to complete the reaction. After reaction, the solvent was evaporated under vacuum and the resulting solid was washed with 5% sodium bicarboinate (20 ml) and 50% ethanol (20 ml). The product recrystallized from ethanol to afford a white solid (71% yield, m.p. 436–437 K). Single crystals suitable for X-ray diffraction were also obtained by evaporation of an ethanol solution.

Refinement top

All the H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H distances of 0.93–0.97 Å, and with 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 > 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.
