Sources of common compounds: 2674-34-2

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, 1,4-Dibromo-2,5-dimethoxybenzene, other downstream synthetic routes, hurry up and to see.

Synthetic Route of 2674-34-2, The chemical industry reduces the impact on the environment during synthesis 2674-34-2, name is 1,4-Dibromo-2,5-dimethoxybenzene, I believe this compound will play a more active role in future production and life.

Example 6: Preparation of 4-bromo-2,2′,5,5′- tetramethoxybiphenyl (6); [00111] In an argon flushed two-neck round-bottom flask, a mixture of 1.02 g (5.0 mmol) of sodium 2,5-dimethoxyphenylboronate, 3.0 g (10 mmol) of 2,5-dibromo-1 ,4-dimethoxybenzene, 60 mg (1 mol%) of tetrakis(triphenylphosphine)palladium, 20 ml of 2 M sodium carbonate and 50 ml of THF was added and heated at reflux for two hours. After cooling, the reaction mixture was extracted with ethyl acetate and the organic phase was EPO washed with brine and dried over magnesium sulfate. After the solvent was removed on a rotary evaporator, the residue was purified by column chromatography eluted with hexane/CH2CI2 (4:1) to give 1.0 g 4-bromo- 2,25,5′-tetramethoxybiphenyl (yield 63%). 1HNMR (CDCI3) 57.187 (s, 1 H), 6.836-6.951 (m, 4 H), 3.869 (s, 3 H), 3,814 (s, 3 H), 3.757 (s, 6 H). 13CNMR (CDCI3) 5153.788, 151.830, 151.596, 150.278, 128.277, 127.995, 117.615, 117.293, 115.897, 113.924, 112.933, 110.019, 57.291 , 57.042, 56.897, 56.171.
