Route of Synthesis (ROS)
| Conditions | Yield |
| With sodium methylate In dimethyl sulfoxide for 48h; Ambient temperature; | 42% |
| Stage #1: Dimethyldisulphide; 3,5-dithiahexan-2-one With sodium methylate In dimethyl sulfoxide at 20℃; for 48h; Stage #2: With hydrogenchloride In water; dimethyl sulfoxide Experimental Procedure Dimethyl disulphide (3.7 g, 38.8 mmol), 3,5-dithiahexan-2one (Ahern, T. P., Haley, M. F., Langler, R. F. and Trenholm, J. E. Can. J. Chem., 1984, 62, 610) (1.0 g, 7.7 mmol) and Me2SO (2 ml) were added. The reaction mixture was stirred at ambient temperature for 2 days. Hydrochloric acid (2.5%, 100 ml) was added and the resultant mixture extracted with diethyl ether (three 100 ml aliquots). The combined organic layers were concentrated and the extraction procedure was repeated. The combined organic layers were dried (MgS04) and filtered, and the solvent was evaporated. [0266] The crude product was chromatographed on silica gel (10 g) employing light petroleum (10 ml fractions) for elution. Fractions 3-7 were combined and the residue was distilled furnishing 2,3,5-trithiahexane (7) (0.45 g, 3.2 mmol, 42%), b.p. 106° C./18 Torr. 1H n.m.r.
