Source of material
In the typical case, 6-methyl-2-pyridinecarboxylic acid (1.2 mmol), N-methyl morpholine (0.4 mmol), and ethylchloroformate (0.4 mmol) were successively added to the 10 mL dry tetrahydrofuran (THF) and stirred at −15 °C for 20 min. After 20 min of stirring, 2-(2-(2-aminophenyl)disulfanyl)-benzenamine (0.3 mmol) was added to the solution, and the reaction mixture was stirred for 2 h at −15 °C. The stirring was later continued at room temperature for an additional 12 h. The reaction was monitored by using thin layer chromatography. After the reaction was completed, the reaction mixture was concentrated to remove the THF and then extracted into ethyl acetate. The organic layer was dried over sodium sulfate and was concentrated under vacuum, to get crude solid, which was recrystallized from chloroform-acetonitrile to get diffraction-quality crystals. Yield 72%. Anal. Calc. for C26H22N4O2S2: C, 64.18; H, 4.56; N, 11.51; S, 13.18; found: C, 64.37; H 4.32; N 11.48; S, 13.15.
Experimental details
Hydrogen atoms were assigned with common isotropic displacement factors Uiso (H) = 1.2 times Ueq (C, benzene ring; N, amide) and Uiso(H) = 1.5 times Ueq(C, methyl carbon). All the H atoms were refined as riding on their parent atom.
Comment
In nature, disulfide compounds have received much attention in the field of coordination chemistry, pharmaceutical chemistry, biochemistry, and organic synthesis [3], [4], [5]. It is particularly noteworthy that the disulfide bonds played an important role in the areas of folding, structure, and stability of the proteins because the S–S bonds are the only readily reversible covalent chemical cross-linking bonds presented in the native proteins [6], [7]. Consequently, the syntheses of new disulfide compounds has become a hot spot. For instance, Sobczak et al. firstly described that the heterodimeric product 1-[(4-chloro-phenyl)disulfanyl]-2-nitrobenzene was synthesized by the reaction of bis 4-chlorophenyl disulfide [(4–ClPhS)2]and bis 2-nitrophenyl disulfide [(2–NO2PhS)2] [8]. Singh’s group synthesized three hexadentate disulfide ligands and tested their performance for binding with library of metal ions [9]. So far, despite some thrilling work has been achieved, newly designed disulfide compounds are long-sought-after yet still unmet.
The molecular structure of the title disulfide compound is shown in the figure. Single crystal X-ray diffraction analysis reveals that the title structure consists of one diphenyl disulfide unit and two (6′-methylpyridine)-2-carboxamide units, in two halves of the molecule (about S–S bond) the phenyl ring and the substituted pyridine are forming very different dihedral angles (31.91(2); 6.60(2)°) between the phenyl plane (C14/C15/C16/C17/C18/C19) and the pyridine plane (C21/C22/C23/C24/C25/N4) and the phenyl plane (C1/C2/C3/C4/C5/C6) and the pyridine plane (C8/C9/C10/C11/C12/N2), respectively, suggesting that one-half is relatively more planar than the other. The torsion angle C1–S1–S2–C14 is 90.32° in the molecular structure of the title compound and shows a kink around the S–S bond making the two halves out of plane with each other. The bond distance of S–S is 2.0758(17) Å, which is similar with that of the reported N,N′-(disulfanediyl-bis(4-(morpholin-4-yl)-2,1-phenylene)) bis(1,3-benzothiazol-2-amine) chloroform solvate [10]. Additionally, the title compound adopts weak π⃛π interactions between the pyridine ring (C21/C22/C23/C24/C25/N4) and phenyl ring (C1/C2/C3/C4/C5/C6) with a centroid to centroid distance as 3.83 Å, which was similar to that of the reported N,N′-(disulfanediyldi-2,1-phenylene)dipyridine-2-carboxamide [11].
