In the title compound, C23H17FO2, the cyclo­hexenone ring has an envelope conformation, the flap atom being the C atom to which the phenyl ring is attached. The 4-fluoro­benzoyl ring and the phenyl ring are inclined to one another by 28.77 (7)°, and by 52.00 (7) and 44.77 (7) °, respectively, to the aromatic ring fused to the cyclo­hexenone ring. In the crystal, mol­ecules are linked via C—H⋯O hydrogen bonds, forming a two-dimensional network lying parallel to (100).

Comment top

Domino reaction as an important tool to construct structurally complicate molecule due to high atom economy and environmental benefits (Zhao et al., 2012). Pd-catalyzed cascade reactions have become an efficient protocol of modern organic synthesis chemistry (Wang et al., 2011; Yu et al., 2012). Condensed polycyclic compounds are playing increasingly important roles as synthetic building blocks, pharmacophores, and electroluminescence materials (Rixson et al., 2012). We have reported some novel cross-coupling reactions of aryl halides with the olefins and diynes (Hu et al., 2009; 2010). The reaction of bromobenzene with 1-(2-((4-fluorophenyl)ethynyl)phenyl)prop-2-en-1-one, in the presence of Pd(II) acetate and triphenylphosphine, in DMF at 418 K for 19 h, gave the unexpected title product.

The crystal structure data of molecule, C31H30N2O, reveals that all the bond lengths and angles have normal values. The titled molecule contains three phenyl ring and one six-membered carbon ring with a boat conformation. One phenyl ring and the cis-fused cyclohexene ring are common side. All the rings are not coplanar (Fig. 1). In the molecule there are two chiral carbon atoms, C9 and C10, but the crystal is a racemic system due to lacking of the chiral separation. In the crystal packing, there are weak intermolecular C–H···O interactions C14–H14···O1i which forms 1-D chain were formed between neighboring molecules along c axis (Fig. 2). Symmetry code: (i) x, -y+1/2, z-1/2.

Experimental top

An oven-dried Schlenk flask was evacuated, filled with nitrogen, and then charged with 1-(2-((4-fluorophenyl)ethynyl)phenyl)prop-2-en-1-one (2.51 g, 10 mmol), bromobenzene (1.72 g, 11 mmol), tributylamine (3 ml), PPh3 (52.5 mg, 0.2 mmol), Pd(OAc)2 (24 mg, 0.1 mol), and DMF (10 ml) to give a yellow solution. The reaction mixture was heated at 418 K with stirring. The reaction mixture was cooled to room temperature after 19 h and the resultant yellow-orange mixture was diluted with Et2O (10 ml). The mixture was washed with H2O (15 ml) and the aqueous layer was extracted with Et2O (20 ml). The combined organic layers were dried (MgSO4), filtered, and concentrated in vacuo. The crude product was purified by flash column chromatography on silica gel (petroleum ester : EtOAc = 9 : 1) and recrystalized from EtOAc, yield 2.45 g (71%). Colourless crystals suitable for X-ray diffraction were obtained by recrystallization from a solution of the title compound from ethyl acetate over a period of one week.

Refinement top

All H atoms were positioned geometrically and refined using a riding model with C–H = 0.93Å-0.98Å with Uiso(H) = 1.2Ueq(C).

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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.
