Reference of 7314-86-5, 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. 7314-86-5 name is 1,3,5,7-Tetrabromoadamantane, 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.
A 250 ml three-necked flask equipped with a condenser was charged with 5.0 g (ie, 11. Ommol) of tetrabromoadamantane and 20 mL (ie, leOmmol) of o-methoxybromobenzene. An inverted funnel was pipetted from the upper end of the condenser to a 30% NaOH aqueous solution to absorb the HBr produced by the reaction. Under 5 C cold water bath, 1.2g (S Jie 4.5mmol) of AlBr3 was added to the reaction system, and the reaction was continued under a cold water bath for 1 hour, then the cold water bath was withdrawn and the reaction was resumed to room temperature for about 3 hours. Finally, the reaction system In the oil bath was heated to 60 C for 4 hours, the reaction was cooled to room temperature, poured into 100mL of acidic ice water and stirred lh.After the ice has completely melted, 100 ml of ethyl acetate is added to the mixture for extraction. The organic layer is washed with water until neutral, washed with saturated brine, dried over anhydrous sodium sulfate, filtered and the filtrate is concentrated. The concentrated solution is then slowly added dropwise to 100 ml Methanol, precipitation, to give a pale yellow solid 6.9g, 72% yield.
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 1,3,5,7-Tetrabromoadamantane, and friends who are interested can also refer to it.
