4-(2,5-Dihexyloxyphenyl)benzoic acid

Abstract top

In the title compound, C25H34O4, one n-hexyl chain of the hexyloxy group adopts a fully extended all-trans conformation, and the other n-hexyl chain displays disorder with site occupancies of 0.470 (3) and 0.530 (3). The dihedral angle between the benzene rings is 44.5 (3)°. In the crystal structure, intermolecular O-H...O hydrogen bonds form dimers via crystallographic inversion centres.

Comment top

Palladium-catalyzed Suzuki coupling reaction has become an extremely powerful method in synthesis for the formation of carbon-carbon bond (Kotha et al., 2002). For example, 1,4-Dibromide-2,5-bis(hexyloxy)benzene was reacted with 4-carboxyphenylboronic acid in the presence of Pd(PPh3)4 to give coupling product 2,5-bis(hexyloxy)-1,4-di(4'-carboxyphenyl)benzene (Zhang et al., 2006). In the above reaction, we obtained the title compound as a side product.

A view of the molecular structure of the title compound is given in Fig.1. The dihedral angle between benzene rings is 44.5 (3)°. One n-hexyl chain of the hexyloxyl group has the same fully extended all - trans conformation as the 1,4-Dibromide-2,5-bis(hexyloxy)benzene (Li, et al., 2008), while the other n-hexyl chain displays disorder with site occupancies 0.470 (3) and 0.530 (3). In the crystal structure, centrosymmetric dimers arise from pairs of O—H···O hydrogen bonds involving the carboxylic acid groups (Fig.2, Table 1).

Experimental top

1,4-Dibromo-2,5-bis(hexyloxy)benzene was prepared as described in the literature (Maruyama & Kawanishi 2002). The title compound was obtained as a side-product from the Suzuki coupling reaction of 1,4-Dibromo-2,5-bis(hexyloxy)benzene and 4-carboxyphenylboronic acid as described in the literature (Zhang et al., 2006) and recrystallized from ethanol at room temperature to give the desired crystals suitable for single-crystal X-ray diffraction.

Refinement top

H atoms attached to C atoms of the title compound were placed in geometrically idealized positions and treated as riding with C—H distances constrained to 0.93 (aromatic CH), or 0.96 Å (methyl CH3), and 0.97 Å (methylene CH2) and constrained to ride on their parent atoms, with Uiso(H) = 1.2 Ueq(C) (1.5Ueq for methyl H).

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.
