Biphenyl (11 mmol) in chloroform (5 ml) was added slowly to a stirred mixture of anhydrous aluminum chloride (4.5 g) and benzoyl chloride (11.5 mmol) in dry chloroform (15 ml), in an ice bath and reaction mixture stirred for half hour. it was further stirred at room temperature for 3 h. Upon completion reaction mixture was diluted with water, extracted with dichloromethane and concentrated. Recrystallization from ethanol afforded (I) in 87% yield as colourless plates: Anal. calcd. for C19H14O: C, 88.34; H, 5.46%; found: C, 88.41; H, 5.61%.

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 > 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. |

Various biphenyl derivatives are used in the synthesis of pharmaceuticals, antifungal agents like bifonazole, optical brightening agents, dyes and polychlorinated biphenyls (PCBs). PCBs are used as heat-transfer agents, as electric insulators and are environmental pollutants causing carcinogenesis. 4-Phenylbenzophenone (4-benzoylbiphenyl) is used in luminescence chemistry, spectrophotometric analysis, molecular chemistry, and as a stating material for organometallic-complexes. 4-Benzoylbiphenyl is the main photoproduct of the photodecomposition of photoinitiator N-[(4-benzoyl)benzene sulfonyl]benzenesulfonamide in an aqueous solution (Kucybala & Wrzyszczynski 2002). Phosphorescence and optically detected magnetic resonance (ODMR) experiments are reported for the lowest excited triplet state of 4-benzoylbiphenyl and related compounds. These compounds have been studied in single-crystal form and have a lowest m* triplet state (van der Velden et al., 1980).
In the title compound, C19H14O, the dihedral angle between the two aromatic rings of the biphenyl residue is 8.0 (3)° and the dihedral angle between the two rings connected by the carbonyl C atom is 51.74 (18)°. There are no short C—H···O contacts.
