The main molecule of the title compound, C37H36·CDCl3, is a hydrocarbon with two naphthalene segments attached to opposite ends of a rigid norbornylogous spacer with an overall structure that is approximately C-shaped. The dihedral angle between the naphthalene ring planes is 9.27 (7)°. The cleft that exists between the naphthalene rings is large enough that the compound crystallizes with a solvent molecule (CDCl3) in the cleft. The CDCl3 solvent molecule is present in two disordered orientations in a 3:2 ratio, each involving C—D⋯π to C6 ring centers.

Triethylsilane (94 µL; 0.588 mmol) and trifluoroacetic acid (44 µL; 0.588 mmol) were added to a stirring suspension of 15,17-di-2-naphthylhexacyclo[10.2.1.13,10.15,8.02,11.04,9]heptadecane-15,17-diol (25 mg; 0.049 mmol) in CH2Cl2 under nitrogen. Upon adding the trifluoroacetic acid, the solid gradually went into solution, and the reaction was refluxed for two hours. Upon cooling, solid sodium bicarbonate was added. After 30 minutes, the reaction mixture was filtered and concentrated under reduced pressure. The crude solid was purified by preparative TLC on silica gel (30% CH2Cl2 in petroleum ether) to give the title compound as the major diastereomer (with evidence of at least one additional diastereomer by NMR) as an off-white solid in 42% yield (10 mg). Single crystals suitable for crystallographic analysis were obtained by slow vapor diffusion of hexanes into a solution of the compound dissolved in chloroform-d at room temperature.
The C and Cl atoms were refined by using anisotropic displacement parameters; occupancies of the two disordered CDCl3 solvates were constrained to sum to 1.0. The H atoms were located in a difference map, initially refined with soft restraints on the bond lengths and angles to regularize their geometry (C—H in the range 0.93–0.98 and Uiso(H) in the range 1.2–1.5 times Ueq of the parent atom), after which only their positional parameters were refined (Uiso(H) fixed).

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. |

The structure of the title compound, C37H36.CDCl3, consists of two naphthalene rings connected to opposite ends of a rigid, norbornylogous hydrocarbon spacer. The overall topology of the molecule is roughly C-shaped, and the cleft that exists between the rings allows for inclusion of a molecule of crystallization, chloroform-d (CDCl3), as shown in Figs. 1 and 2. Although the naphthalene rings can rotate freely about the C—C bond through which they are attached to the rigid spacer, they are only found in a cofacially stacked, eclipsed conformation. The anti conformer is not observed. The CDCl3 within the cleft is in two disordered orientations, occurring in about a 3:2 ratio. Both orientations show interactions with different areas of the naphthalene rings. The most common orientation shows coordination between the chloroform deuterium atom and the π system of the distal ring of the naphthyl group. In this orientation, the C···π and D···π distances are 3.399 and 2.44 Å, repectively, with a C—D···π angle of 172.7°. In the other orientation, the C···π and D···π distances are 3.521 and 2.61 Å, repectively, with a C—D···π angle of 153.9°. To establish the context for the measurements associated with this interaction, the Cambridge Structural Database (Allen, 2002: Version 5.30, including May 2009 updates) was searched for homologous structure-solvent motifs. The search results are organized into two histograms, one for the H(D)···π distance (Fig. 3) and one for the C—H(D)···π angle (Fig. 4). The histograms support the observations, with the values for distance and angle falling well within the range of previously observed values. The observed C···π distance of 3.399 Å was on the low end of recorded distances, whereas the angle of 172.7° was binned at the higher end of the angle range.
