Abstract top

The asymmetric unit of the title compound, C25H25NO2, contains two independent molecules. The crystal packing exhibits weak intermolecular C-H...O, C-H...[pi] and [pi]-[pi] interactions.

Comment top

The "Grindstone Chemistry" method for conducting exothermic reactions in the solvent-free mode has been recently published (Bose et al., 2004). When this protocol was applied to the Pechmann synthesis on a multi-molar scale, the expected coumarins were obtained in a few minutes as pure products in high yield by solvent-free grinding. Since this reaction proved to be exothermic, we tested energy-saving procedures developed in our laboratory for the preparation of 1,5-diketones starting from the fragrant aldehydes and fragrant ketones in the presence of NaOH under solvent-free conditions. Using this method, we obtained the title compound, (I). Herewith we present its crystal structure.

In (I), all bond lengths and angles are normal and correspond to those observed in 1,3,5-triphenyl-pentane-1,5-diketone (Das et al., 1994) and 1,5-diphenyl-3-(2-pyridyl)pentane-1,5-dione (Huang et al.cv2222435, 2006). The asymmetric unit of (I) contains two independent molecules (Fig. 1) with different conformations - the dihedral angles formed by two phenyl rings in each molecule are 85.48 (7) and 71.26 (7)°, respectively.

The weak intermolecular π–π (Table 1) and C—H···π (Table 2) interactions, and C—H···O hydrogen bonds (Table 2) contribute to the crystal packing stabilization.

Experimental top

Acetophenone (6.25 mmol) and 4-(dimethylamino)benzaldehyde (3.125 mmol), NaOH (6.25 mmol) were aggregated with glass paddle in an open flask. The resulting mixture was washed with water for several times for removing NaOH, and recrystalized from ethanol, and afforded the title compound as a crystalline solid. Elemental analysis: calculated for C25 H25 NO2: C 80.83, H 6.78, N 3.77%; Found: C80.88, H 6.83, N3.65%.

Refinement top

All H atoms were positioned geometrically (C—H 0.93–0.98 Å) and refined using a riding model, with Uiso(H) = 1.2-1.5Ueq(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.
