Abstract top

In the title compound, C26H22ClFO2, the cyclopropane ring is disordered over two orientations, with site-occupancy factors of 0.64 (2) and 0.36 (2). The major occupancy component of the cyclopropane ring makes dihedral angles of 47.6 (7), 50.4 (7) and 65.4 (7)° with the fluoro-, chloro- and unsubstituted benzene rings, respectively [the corresponding values for the minor occupancy component are 47.6 (12), 51.0 (12) and 60.9 (12)°]. An intramolecular C-H...O hydrogen bond occurs. The F and Cl atoms deviate by 0.0508 (12) and 0.0592 (7) Å from the planes of their attached benzene rings. In the crystal, C-H...F hydrogen bonds link the molecules into chains along the b-axis direction.

Comment top

Diketones are popular in organic synthesis for their applications in biology and medicine. They are known to exhibit antioxidants, antitumour and antibacterial activities (Bennett et al., 1999). They are also key intermediates in the preparation of various heterocyclic compounds (Sato et al., 2008).

In the title compound (Fig. 1), the cyclopropane ring (C1-C3) is disordered over two positions with the site occupancy factors of 0.64 (2):0.36 (2), representing to major and minor components, respectively. The cyclopropane ring (C1-C3) makes a dihedral angle of 47.6 (7)° with the fluoro substituted phenyl ring (C6-C11). It makes a dihedral angle of 50.4 (7)° with the chloro substituted phenyl ring (C13-C18) and a dihedral angle of 65.4 (7)° with the unsubstituted phenyl ring (C21-C26). The fluorine atom (F1) attached with the phenyl ring deviates by 0.0508 (12)Å.

The dihedral angle between the fluoro substituted phenyl ring and the chloro substituted phenyl ring is 6.50 (9)° and the dihedral angle between the fluoro substituted phenyl ring and the unsubstituted phenyl ring is 64.52 (10)°. The dihedral angle between the chloro substituted phenyl ring and the unsubstituted phenyl ring is 70.89 (10)°. The chlorine atom (Cl1) attached with the phenyl ring deviates by 0.0592 (7)Å. The packing of the crystal is stabilized by C–H···F hydrogen bonds.

Experimental top

A mixture of acetophenone (0.01 mole), 4-chlorobenzaldehyde (0.01 mole), cyclopropyl 2-fluorobenzyl ketone (0.01 mole) and sodium hydroxide solution (10 ml, 10%) in ethanol (50 ml) was stirred for 3 hrs at room temperature. The solid that separated was filtered and washed with distilled water. The product was recrystallised from ethanol. Yield=96%, melting point = 418-421 K. Single crystals suitable for X-ray diffraction were obtained by slow evaporation of a solution of the title compound in ethanol at room temperature.

Refinement top

The cyclopropane ring was disordered over two positions with the site occupancy factors of 0.64 (2):0.36 (2). The bond distances of the disordered components were restrained using standard similarity restraints SADI [SHELXL97, Sheldrick, 2008] with s.u. of 0.01 Å. The hydrogen atoms were placed in calculated positions with C—H = 0.93 to 0.98 Å and refined in the riding model with fixed isotropic displacement parameters: Uiso(H) = 1.5Ueq(C) for methyl group and Uiso(H) = 1.2Ueq(C) for other groups.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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.
