In the title compound, C34H28N2S2, the central imidazole ring (r.m.s. deviation = 0.0015 Å) forms dihedral angles of 55.7 (3), 17.94 (11) and 86.27 (11)°, respectively, with the mean planes of the attached thienyl and two phenyl substituents. The thienyl ring shows ring-flip disorder [occupancy ratio = 0.647 (2):0.353 (2)]. The chiral centre maintains the S configuration of the L-phenylalaninol starting material. Intra- and intermolecular C—H⋯S hydrogen bonds involving the disordered thienyl ring are observed.

NaH (0.048 g, 2 mmol) was added to an anhydrous 1,4-dioxane (20 ml) solution containing compound I (0.087 g, 0.2 mmol) and the mixture was kept at r.t. for 0.5 h. p-Toluenesulfonyl chloride (0.114 g, 0.6 mmol) was then added and the reaction was followed by TLC detection until the raw material disappeared. Evaporation of the solvent gave the crude product of p-toluenesulfonate (II), which was then purified by silica
In a 50 ml flask, p-toluenesulfonate (II, 0.295 g, 0.5 mmol), thiophenol (0.110 g, 1 mmol), cuprous iodide (0.001 g, 0.005 mmol), and potassium hydroxide (0.056 g, 1 mmol) were dissolved in 1,4-dioxane (10 ml), and the solution was heated to 120°C for 12 h under an argon atmosphere. The volatile compounds were then removed in vacuo and a brown, oily residue remained, which was purified by silica Crystallization in MeOH afforded colourless crystals of the title compound (III).The S–C and C—C bond distances involving the disordered S1, S1A, C32, C32A, C33, C33A and C34A atoms were constrained to be 2.5 (2) and 1.4 (2) Å, respectively. The ADPs of atom C17 were restrained to be nearly isotropic. H atoms were placed geometrically and refined as riding, with C—H = 0.93–0.98 Å, and with Uiso(H) = 1.2 Ueq(C).

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. |

Aryl sulfides are important organic compounds with biological, pharmaceutical, and materials interest. Among various methods for the preparation of S-containing compounds, transitionmetal-catalyzed C—S formation has become the most versatile strategy in modern organic chemistry (Mispelaere-Canivet et al., 2005; Zhang et al., 2007; Wu et al., 2009; Lv et al., 2007). Our group is interested in the synthesis and application of chiral imidazolium derived from natural amino acids (Mao et al., 2010; Yang et al., 2012; Xiao et al., 2012; Gao et al., 2013). During the study, we observed that the condensation of L-phenylalaninol, dibenzoyl, thiophene-2-carbaldehyde and ammonium acetate afforded (S)-2-(4,5-diphenyl-2-(thiophen-2-yl)-1H-imidazol-1-yl)-3-phenylpropan-1-ol (I), which was converted to p-toluenesulfonate (II) upon treatment with p-toluensulfonyl chloride. The following reaction of II with thiophenol catalyzed by CuI under basic condition produced the title compound (III) smoothly.
The molecular structure of the title compound (III) is shown in Figure 1. The imidazole ring (C7/C8/N2/C30/N1) is essentially planar, the maximum deviation being 0.002 (2) Å for atom C7. The thienyl ring shows ring-flip disorder, the major and minor components of the disorder having an occupancy factor of 0.647 (2) and 0.353 (2), respectively. The dihedral angle between the mean plane through the thienyl ring and the imidazole ring is 55.7 (3)°. The dihedral angles between the two phenyl substituents (C1—C6, C9—C14) and the imidazole ring are 17.94 (11) and 86.27 (11)°. The chiral C22 carbon atom maintains the S configuration of the L-phenylalaninol starting material. In the crystal structure, intra- and intermolecular C—H···S hydrogen bonds involving the disordered thienyl ring (Table 1) are observed.
