All reagents and solvents were obtained from commercial sources and needed to be further purified. 1,2-bis(o-tolyloxy)ethane was synthesized according to the method proposed by Yuan et al. (2005). 1,2-Bis(2-(bromomethyl)phenoxy)ethane was prepared following previously reported methods, but with some modification (Siva & Murugan, 2005; Gruter et al., 1994). 1,2-Bis-(o-tolyloxy)ethane (10 mmol), N-bromosuccinamide (30 mmol), benzoyl peroxide (20 mmol) and CCl4 (50 ml) were taken in a 100 ml round-bottom flask. The reaction mixture was refluxed for 6 h under an IR lamp (250 W) irradiation. Subsequently, the solid formed in the reaction was removed by fltration. The solvent was evaporated under vacuum to give the crude product, which was thereafter recrystallized (ethanol-acetone) to prodcue pale-yellow needles, yield: 76%. The title compound was synthesized according to the related literature (Kumar et al., 2005). A mixture of 2-mercaptobenzothiazole (4 mmol), 1,2-bis(2-(bromomethyl)p-henoxy)ethane (2 mmol) and finely grounded anhydrous K2CO3 (4 mmol) in acetone was refluxed for 2 h (TLC monitoring). The reaction mixture was then cooled to room temperature and filtered. Evaporation of the filtrate yielded the crude products. Finally, the crude products were purified by recrystallization from the hexane-ethyl acetate solution, yield: 84%.
H atoms were placed in calculated positions and were refined in a riding-model approximation with C—H = 0.93 or 0.97 Å and with Uiso(H) = 1.2Ueq(C).
It is reported that benzothiazoles and their derivatives have showed a wide variety of biological activities, such as anti-inflammatory, antimycobacteriva, and capability of labeling cancer cells (Paramashivappa et al., 2002; Kočí et al., 2002; Fei et al., 2009). As an important class of benzothiazoles, benzothiazole-2-thiol also exhibits potential biological activities. Therefore, the title compound was synthesized.
In the title compound (Fig. 1), the dihedral angles between each benzene ring and benzothiazole ring pair where the two rings are linked to each other are 87.00and 60.18°, respectively, while the dihedral angle between the two benzene rings is 13.63°. The stability of the structure is ascribed to the weak C—H···π interactions. In the crystal (Fig. 2), the molecules are linked by weak C—H···π interactions and intermolecular S···S interactions.

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. |

It is reported that benzothiazoles and their derivatives have showed a wide variety of biological activities, such as anti-inflammatory, antimycobacteriva, and capability of labeling cancer cells (Paramashivappa et al., 2002; Kočí et al., 2002; Fei et al., 2009). As an important class of benzothiazoles, benzothiazole-2-thiol also exhibits potential biological activities. Therefore, the title compound was synthesized.
In the title compound (Fig. 1), the dihedral angles between each benzene ring and benzothiazole ring pair where the two rings are linked to each other are 87.00and 60.18°, respectively, while the dihedral angle between the two benzene rings is 13.63°. The stability of the structure is ascribed to the weak C—H···π interactions. In the crystal (Fig. 2), the molecules are linked by weak C—H···π interactions and intermolecular S···S interactions.
