In the title compound, C15H14O3, the dihedral angle between the benzene rings is 75.85 (7)°. In the crystal, centrosymmetrically related molecules are weakly associated through pairs of interactions between a benzene ring and an O atom of the ester group [ring centroid⋯O = 3.952 (7) Å], and through pairs of interactions between the other benzene ring and an O atom of the phenoxy group [ring centroid⋯O = 3.912 (7) Å], giving chains extending along [110].

Benzoic acid (10.0 g, 0.08 mol) was mixed directly without solvent with 2-phenoxyethanol (11.0 g, 0.08 mol) and refluxed for 3 hours. The reaction was left at room temperature for 24 hours. The product was collected as crystals in 52% yield. The crystals were purified by washing several times with cold ethanol.
Hydrogen atoms were positioned geometrically with C—H = 0.93 Å (aromatic) or 0.98 Å (methylene) and allowed to ride in the
with Uiso(H) = 1.2Ueq(C).Phenoxyethyl benzoate has applications in the synthesis of e.g. oxazoles, imidazoles and benzoxazepines (Huang et al., 1996; Gandhi et al., 1995).
are also useful as photo-removable protecting groups for in organic synthesis and biochemistry (Ruzicka et al., 2002; Litera et al., 2006; Sheehan & Umezaw, 1973). Keeping this in view, the title compound, C15H14O3, was synthesized and its is repored herein.In the title compound (Fig. 1), the dihedral angle between the benzene rings is 75.85 (7)°. In the crystal, two centrosymmetrically related molecules are weakly associated through a pair of intermolecular interactions between a benzene ring [C1–C6] and an oxygen of the phenoxy group (O1A) [ring centroid(Cg)···O1A separation, 3.912 (7) Å] [for symmetry code (A): -x, -y + 1, -z]. In addition, the molecules are weakly associated through a similar pair of intermolecular interactions between the second benzene ring [C10–C15] and a carboxyl oxygen of the ester group (O2B) [ring centroid (Cg)···O2B separation, 3.952 (7) Å] [for symmetry code (B): -x + 1, -y, -z] (Fig. 2). The result is a chain structure extending across [110].

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. |

Phenoxyethyl benzoate has applications in the synthesis of e.g. oxazoles, imidazoles and benzoxazepines (Huang et al., 1996; Gandhi et al., 1995). Esters are also useful as photo-removable protecting groups for carboxylic acids in organic synthesis and biochemistry (Ruzicka et al., 2002; Litera et al., 2006; Sheehan & Umezaw, 1973). Keeping this in view, the title compound, C15H14O3, was synthesized and its crystal structure is repored herein.
In the title compound (Fig. 1), the dihedral angle between the benzene rings is 75.85 (7)°. In the crystal, two centrosymmetrically related molecules are weakly associated through a pair of intermolecular interactions between a benzene ring [C1–C6] and an oxygen of the phenoxy group (O1A) [ring centroid(Cg)···O1A separation, 3.912 (7) Å] [for symmetry code (A): -x, -y + 1, -z]. In addition, the molecules are weakly associated through a similar pair of intermolecular interactions between the second benzene ring [C10–C15] and a carboxyl oxygen of the ester group (O2B) [ring centroid (Cg)···O2B separation, 3.952 (7) Å] [for symmetry code (B): -x + 1, -y, -z] (Fig. 2). The result is a chain structure extending across [110].
