The mixture was then poured on ice (?250 mL), the dark purple mixture was allowed to warm up to rt, transferred into a 500 mL round-bottom flask and refluxed for 1 h. The resulting suspension was cooled down to rt, filtered through a layer of Celite, a solution of ZnCl2 (80 g in 150 mL water) was added and the mixture was left at 4 C. overnight. A dark red oil, containing the crystals of 3,6-bis(dimethylamino)thioxanthylium trichlorozincate [prepared according to WO 2010067078 A2 and Heterocyclic Chemistry, 1966, 3, p. 228], separated. The colorless supernatant was decanted off, the residue was dissolved in boiling water (150 mL) and NaClO4 solution (5 g in 10 mL water) was added. The resulting suspension was allowed to cool down to rt and then left in ice-water bath to complete crystallization. The crystals were filtered off, washed with water, Et2O/hexane (1:1) and Et2O, dried in vacuo. Small brown crystals, yield 606 mg (4%). MS (ESI): m/z (positive mode, rel. int., %)=283.1 (100) [M]+. |
