As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 2695-47-8 name is 6-Bromo-1-hexene, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below. 2695-47-8
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 ¡Á 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.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 6-Bromo-1-hexene, and friends who are interested can also refer to it.
