2,2-Dimethyl-5-(4-trifluoromethyl-benzyl)-[1,3]dioxane-4,6-dione (1 mmol), acetonitrile (25 ml) and water (0.25 ml) were mixed and subjected to microwave irradiation at 120° for 30 min (150 psi, 300 W, run time 5 min, hold time 30 min). Crude compound (I) was obtained. An X-ray grade crystal of (I) (500 mg) was grown from ethyl ether (10 ml) at room temperature.
H atoms were placed geometrically at the distances of C—H = 0.93–0.97 Å and O—H = 0.82 Å, and included in the
in riding motion approximation with Uiso(H) = 1.2 or 1.5Ueq of the carrier atom.Data collection: CAD-4 EXPRESS (Enraf–Nonius, 1994); cell

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. |

Some derivatives of acids is important chemical material (Battistuzzi et al., 2003; Feuerstein et al., 2003, 2001; Johnson & Wen, 1981; Yamanouchi & Yamane 1988; Shoda & Kuriyama, 2003). We report here the crystal structure of the title compound, (I). The molecular structure of (I) is shown in Fig. 1, and the selected geometric parameters are given in Table 1. The bond lengths and angles (Table 1) are within normal ranges (Allen et al., 1987).
In the crystal of the title compound, there is an intermolecular O—H···O hydrogen bond which may be effective to the stabilization of the crystal.
