Electric Literature of 2695-47-8,Some common heterocyclic compound, 2695-47-8, name is 6-Bromo-1-hexene, molecular formula is C6H11Br, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: A 70 ml oven dried autoclave containing a stirrer bar wascharged the AgI (0.5 mg, 0.002 mmol) and Cs2CO3 (978 mg, 3.0mmol). The autoclave was purged three time with CO2 and theterminal alkynes 1 (2.0 mmol), bromides 2 (3.0 mmol), and dryDMF (20 ml) were then added sequentially via a syringe. Theautoclave was then sealed and pressurized to the appropriatepressure with CO2. The reaction mixture was then stirred at 60C for 24 h and the autoclave was cooled to room temperatureand the remaining CO2 slowly vented from the system. Thereaction mixture was diluted with water (30 ml) and extractedwith ethyl acetate (30 ml × 3). The combined organic layerswere washed with water and brine, dried over Na2SO4, andfiltered. The solvent was removed under vacuum. The productwas isolated by column chromatography on silica gel.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 6-Bromo-1-hexene, its application will become more common.
