Related Products of 25245-34-5, The chemical industry reduces the impact on the environment during synthesis 25245-34-5, name is 2-Bromo-1,4-dimethoxybenzene, I believe this compound will play a more active role in future production and life.
Example 7: Preparation of 4,4′-dibromo-2,2′,5,5′- tetramethoxybiphenyl (7); [00113] In a 100 ml round-bottom flask, 3.0 g of FeCI3 in 20 ml of CH2CI2 was added to a solution of 5.0 g of 2,5-dimethoxybromobenzene in 50 ml of CH2CI2. The reaction mixture was stirred overnight, and then it was washed with water and brine and dried with magnesium sulfate. The solvent was removed on a rotary evaporator and the residue was purified by column chromatography eluted by hexane/CH2CI2 (3:1) to obtain 3.4 g of 4,4′- dibromo-2,2′,5,5′-tetramethoxybiphenyl (yield 68%) 1HNMR (CDCI3) 57.194 (s, 2 H), 6.841 (s, 2 H), 3.877 (s 3 H), 3.757 (s, 3 H).
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-Bromo-1,4-dimethoxybenzene, other downstream synthetic routes, hurry up and to see.
