Added 3,3-dimethylbutan-2-one (0.0105 mol) to a solution of 4-dichlorobenzaldehyde (0.01 mol) and 60 ml ethanol drop-wise. Then added 0.1 g 50% NaOH solution as catalyst and stirred at 333 K for 4 h (monitored by TLC). A part of solvent was evaporated, then cooled the mixture to 277 K and the precipitate formed were filtered and dried, giving the desired product (yield: 92.1%). Crystals suitable for X-ray
were obtained by slow evaporation of an ethanol solution at room temperature.The methyl H atom were positioned geometrically (C—H=0.98 Å) and torsion angles refine to fit the electron density [Uĩso~(H) = 1.5U~eq~(C)]. Other H atoms were placed in calculated position (methylene C—H=0.95Å and aromatic C—H=0.95 Å) and refine as riding [Uĩso~(H) = 1.2U~eq~(C)].

Experimental. 1H NMR(400MHz, CDCl3),delta:1.23(s, 9H, 3×CH3),7.09(d, J= 1.52Hz, 1H, 2-CH), 7.36(d, J=8.4Hz, 2H, benzene 3,5-H), 7.5(d, J= 8.4Hz, 2H, benzene 2,6-H), 7.60(d,J=15.6Hz, 1H, 1-CH). |
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 title compound, 1-(4-chlorophenyl)-4,4-dimethylpentan-3-one, is a very important intermediate in the pesticides industry (Wang et al., 2006). Continuing our work (Xia & Hu 2008) we have now synthsized the title compound, (I). In this article we report the synthesis and crystal structure of (I). Several crystal structures containing phenylprop-2-en-1-one moiety have been recently published, e.g., Anuradha et al. (2008); Butcher et al. (2007); Gong et al. (2008); Harrison et al. (2007); Patil et al. (2007); Sarojini et al. (2007); Thiruvalluvar et al. (2007); Thiruvalluvar et al. (2008); Xia & Hu (2008).
In the title compound (Fig. 1), the carbonyl and ethenyl groups are not coplanar with the benzene ring; the mean planes of the carbonyl group (atoms O1/C2/C3/C4) and ethenyl group (atoms C2, C3, C4 and C8) are inclined at 35.37 (5) and 36.27 (11) °, respectively, with the mean-plane of the phenyl ring (C8-C13). The bond lengths and bond angles in (I) are in excellent agreement with the corresponding bond lengths and angles reported in the related compounds given above. The molecules are packed in an offset face-to-face arrangement showing π–π stacking interaction involving the benzene rings with centroid-to-centroid distance = 3.586 (4) Å. The structure is devoid of any classical hydrogen bonds (Fig. 2).
