Abstract

The title mol­ecule, C19H19FO2, exits in the enol form with a dihedral angle of 33.06 (8)° between the two benzene rings. The mol­ecular conformation is stabilized in part by an intra­molecular O—H⋯O hydrogen bond.

Comment

1,3-Diketones are interesting due to their enolic tautomeric forms and their ability to form strong intermolecular or intramolecular hydrogen bonds (Bertolasi et al., 1991; Vila et al., 1991). They are used widely in the chemistry of metallocomplexes (Baskar et al., 2005; Bassett et al., 2004; Jang et al., 2006; Soldatov et al., 2003). The title compound (I) (Fig. 1), is in the enol form stabilized by an intramolecular O-H···O hydrogen bond (see Table 1).

Experimental

1-(4-fluorophenyl)ethanone (1.38 g, 0.01 mol), methyl 4-tert-butylbenzoate (1.92 g, 0.01 mol), NaNH2 (0.78 g, 0.02 mol) and dry ether (60 ml) were placed into round bottom flask. The mixture was stirred for 6 h at room temperature under a blanket of nitrogen, acidified with dilute hydrochloric acid, and stirring was continued until all solids dissolved. The ether layer was separated and washed with saturated NaHCO3 solution, dried over anhydrous Na2SO4 and was removed by evaporation. The residual solid was recrystallized from ethanol solution to give the title compound (I) (yield 1.78 g, 59.6%, m.p. 388 K). Crystals suitable for X-ray diffraction were grown by slow evaporation of a CHCl3—EtOH (1:4) solution of the title compound at room temperature.

Refinement

H atoms were placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H distances of 0.93 to 0.96 Å, and with Uiso(H) = 1.2 Ueq(C). The H atom of the hydroxyl group was located in a difference Fourier map and its position was refined freely, with Uiso(H) = 1.5 Uiso(O).

Special details

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.
