4'-hydroxy-4-biphenylaldehyde (02) was prepared (Chamontin et al. 1999), starting from 4'-bromo-4-biphenol (01) which is commercially available, using the N-formylpiperidine as electrophilic agent. After 4'-hydroxy-4-biphenylaldehyde (02) was acetylated with the acetylating agent acetic anhydride, catalyzed by 4-(dimthylamino)pyridine (DMAP), the target material 4'-formylbiphenyl-4-ylacetate (B3) was obtained (Chakraborti et al. 2003; Steglich et al. 1969).

All H atoms were positioned in calculated positions, with C—H distancesof 0.97 Å, and with Uiso~(H) = 1.2 or 1.5 Ueq~(C). In the abscense of significan anomalous effects, Friedel pairs were merged, thus giving rise to a poorer reflections to parameters ratio.
4'-formylbiphenyl-4-yl acetate is a derivative of biphenyl that contains two phenyl groups joined by a single π-π conjugation (aldehyde group, oxygen group) as compared with unsubstituted biphenyl, and as result the two phenyl groups tend to be more coplanar.
However, rotation about the single bond in biphenyl may be sterically hindered and the equilibrium torsional angles in the variously substituted derivatives may be different. In the case of unsubstituted biphenyl, the equilibrium torsional angle is 44.4°. However, in the title compound its value is 30.39 (1)°, because conjugated effects in the molecule are strengthened byThe molecule of the title compound is illustrated in Fig. 1. The
contains two six-member rings and one acetate group. In the there are no classic hydrogen bonds but there are non-classical intermolecular C—H···O hydrogen bonds (viz., C15—H15C···O3[-x,1/2+y,2-z],H···O: 2.41Å, C—H···O: 177°) which help in forming a three dimensional structure.For details fn the synthetic procedure, see: Chakraborti & Gulhane (2003); Chamontin et al. (1999); Steglich & Höfle (1969).

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. |

4'-formylbiphenyl-4-yl acetate is a derivative of biphenyl that contains two phenyl groups joined by a single covalent bond. However, rotation about the single bond in biphenyl may be sterically hindered and the equilibrium torsional angles in the variously substituted derivatives may be different. In the case of unsubstituted biphenyl, the equilibrium torsional angle is 44.4°. However, in the title compound its value is 30.39 (1)°, because conjugated effects in the molecule are strengthened by π-π conjugation (aldehyde group, oxygen group) as compared with unsubstituted biphenyl, and as result the two phenyl groups tend to be more coplanar.
The molecule of the title compound is illustrated in Fig. 1. The asymmetric unit contains two six-member rings and one acetate group. In the crystal structure there are no classic hydrogen bonds but there are non-classical intermolecular C—H···O hydrogen bonds (viz., C15—H15C···O3[-x,1/2+y,2-z],H···O: 2.41Å, C—H···O: 177°) which help in forming a three dimensional structure.
