| | 2,3,6,7,14,15-Hexabromo-9,10-dihydro-9,10-[1,2]benzenoanthracene Usage And Synthesis |
| Uses | 2,3,6,7,14,15-Hexabromo-9,10-dihydro-9,10-[1,2]benzenoanthracene can be used as impurity standard and reference substance, mainly used in laboratory research and development process and chemical production process middle. | | Synthesis | 
Triptycene (1.06 g, 4.18 mmol) was dissolved in chloroform (80 mL) in a round-bottom flask. Iron filings (30 mg) were added, and the solution was stirred at 25 ??C. Bromine (1.35 mL, 26.3 mmol) was added, and the solution was refluxed for 1 h, during which time the initially reddish-brown solution turned reddish-orange. The flask was removed from heat, and chloroform and excess bromine were removed under vacuum. The resulting brown powder was dissolved in chloroform (100 mL) and flushed through a pad of silica using additional chloroform as eluent (100 mL). The filtrate was evaporated to dryness. The crude white powder (2.83 g, 98%) was crystallized from acetone yielding C20H8Br6 ?¤ (acetone)2 (0.88 g, 29%), mp >350 ??C. The mother liquor was evaporated and the residue was crystallized from acetone to afford a second crop of crystals (0.97 g, C20H8Br6 ?¤ (acetone)2, 32%). The combined yield was 1.85 g, 61%: 2-H yield 2.83 g, 98% |
