1,3,5-Tris(phenylthiomethyl)-2,4,6-trimethylbenzene

J.-R. Li, Z. Yan, M. Du, Y.-B. Xie, R.-H. Zhang and X.-H. Bu

The molecular structure of the title compound, C₃₀H₃₀S₃, adopts a cis, trans, trans-conformation for the three phenylthio groups about the central benzyl ring, which is analogous to a `soft-shelled crawling turtle'. The dihedral angle between the `head' phenyl ring and the central phenyl ring is 89.0 (4)°, while the angles between the two `foot' phenyl rings and the central ring are 18.0 (6) and 6.7 (4)°, respectively.

Crystal engineering and supramolecular chemistry aimed at developing systems to perform optical, magnetic and electronic functions as well as intercalation systems for ion- or molecule-exchange and catalytic properties are some of the most attractive research areas in present years, and much progress has been achieved in both theoretical studies and their applications as new materials (Yuge et al. 1996). One of the most remarkable developments in crystal engineering may be the possibility to select suitable building blocks to assemble into structures with specific topologies (Goodgame et al., 1993; Gormley et al., 2000). Multithioether ligands possess unusual potential for structure control in inorganic chemistry, and a lot of unusual crystal structures of complexes with multithioether ligands (Bu et al., 2002; Alcock et al., 1978) have been reported. There are, however, just a few examples of organic ligands of multithioether whose crystals have been structurally characterized (Gormley et al., 2000). In recent years, one of our interests has been to further study the complexing abilities and the reactivities of a few types of dipodal or tripodal flexible ligands including disulfoxide, trisulfoxide, dithioether, trithioether, and their derivatives. As part of our structural studies of the trithioether series, we report here the synthesis and structure of a new flexible tripodal ligand, 1,3,5-tris(phenylthiomethyl)-2,4,6-trimethylbenzene, (I); more work on the reaction with transition metal ions is still in progress.

The title molecule has a cis, trans, trans-conformation (Fig. 1) for the three phenylthio groups about the central phenyl ring, which is analogous to a `soft-shelled crawling turtle'. The phenylthio 1 (composed of S1 and C21—C26) and 2 (composed of S2 and C31—C36) are on the same side of the central phenyl ring, when viewed together with the two adjacent methyl groups (C11 and C12), would consist of the four feet of this `soft-shelled turtle'. While phenlythio 3 (S3, C41—C46) is on the other side of the phenyl ring, which forms the head held high. The remaining methyl group (C10) would be the tail. The dihedral angle between the head phenyl ring (phenyl 3) and the central phenyl ring is 89.0 (4)°, while the angles between the other two phenyl rings (phenyl 1 and 2) and the central phenyl ring are 18.0 (6) and 6.7 (4)°, respectively, and the dihedral angle between the two rear foot phenyl rings (phenyl 1 and 2) is 21.3 (3)°. All the above shows that whole molecule is assuredly like a `soft-shelled crawling turtle'.

Experimental top

1,3,5-Tris(bromethyl)-2,4,6-trimethylbenzene was prepared according to a reported procedure and was characterized by NMR and IR analysis, giving results consistent with those in the literature (van der Made et al., 1993). Phenylthio-potassium was obtained by the reaction of KOH with thiophenol in warm EtOH. 1,3,5-Tris(phenylthiomethyl)-2,4,6-trimethylbenzene, (I), was synthesized by the reaction of 1,3,5-tris(bromethyl)-2,4,6-trimethylbenzene and thiophenyl-potassium in EtOH at 353 K; yield: 86%; m.p. 381–383 K; IR (KBr): 2957(w), 2921(w), 1584(m), 1572(m), 1479(s), 1438(s), 1226(m), 1091(m), 1024(m), 755(s), 689(s), 471(w)cm^-1; ¹H NMR (CDCl₃): δ 2.45 (3H, s), 4.19 (2H, s), 7.22–7.40 (5H, m); analysis calculated for C₃₀H₃₀S₃: C 73.00, H 6.21%; found: C 73.12, H 6.18%. Colorless single crystals of (I) were obtained by recrystallization from acetonitrile.

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.
