Abstract top

There are two independent molecules in the asymmetric unit of the title compound, C15H12BrNO2. In both molecules, the two benzene rings adopt a cis configuration with respect to the epoxy ring. In one molecule, the epoxy ring makes dihedral angles of 60.5 (2) and 77.92 (19)° with the two benzene rings; in the other molecule, the values are 61.0 (2) and 81.43 (19)°. Intermolecular N-H...O and C-H...O hydrogen bonding is present in the crystal structure.

Comment top

α, β-Epoxy carbonyl compound are important intermediates for the synthesis of complex molecules. (Diez et al. 2008; Watanabe et al. 1998). The Darzens reaction, is one of the most powerful method to the synthesis of α, β-epoxy carbonyl and related compounds (Zhu et al. 1995). We report herein the crystal structure of the title compound.

The molecular structure of (I) is shown in Fig. 1. Bond lengths and angles in (I) are normal. The asymmetric unit of the title compound consists of two crystallographically independent molecules (Fig. 1) each of which adopts a cis configuration about the epoxides ring. The dihedral angle between the C1—C6 and C10—C15 is 86.13 (10)° and that between C16–21 and C25–30 phenyl ring is 83.86 (11)°. O2/C7/C8 epoxide ring makes dihedral angles of 60.47 (22)° and 77.92 (19)° with C6 and C15 phenyl ring, respectively. O3/C22/C23 epoxide ring makes dihedral angles of 60.96 (22)° and 81.43 (19)° with C16 and C25 phenyl ring, respectively. The crystal packing is stabilized by N—H···0 and C—H···0 hydrogen bonding (Table 1).

Experimental top

2-Chloro-N-phenylacetamide (0.17 g, 1.0 mmol) and potassium hydroxide (0.112 g, 2.0 mmol) were dissolved in acetonitrile (2 ml). To the solution was added 3-bromophenylaldehyde (0.15 g, 1.0 mmol) at 298 K, the solution was stirred for 60 min and removal of solvent under reduced pressure, the residue was purified through column chromatography. Single crystals suitable for X-ray diffraction were obtained by slow evaporation of an ethyl acetate solution at room temperature for 1 d.

Refinement top

H atoms on N atoms was located in a difference Fourier map and refined isotropically with distance restraints of 0.90±0.01 Å. The carbon-bound hydrogen atoms were placed in calculated positions with C—H = 0.93–0.98 Å and refined using a riding model, Uiso(H) =1.2Ueq(C). The distance restraints of 1.39±0.01 Å were applied for the C—C bonds of the benzene rings.

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.
