1-Bromo-2,5-dimethoxybenzene Chemical Properties,Usage,Production

Chemical Properties

clear colorless to yellowish liquid

Uses

2-Bromo-1,4-dimethoxybenzene has been used in preparation of S-(-)-2-[N-(trifluoroacetyl)amino]-1-(2,5-dimethoxy-4- bromophenyl)-1-propanone, 1,4-bis{4-[2-(4-pyridyl)ethenyl]phenyl}butadiyne and 1,4-bis{2,5-dimethoxy-4-[2-(4-pyridyl)ethenyl]phenyl}butadiyne and 1-bromo-4-iodo-2,5-dimethoxybenzene. It can be used as a chemical redox shuttle additive in Lithium ion batteries for repeated overcharge and overdischarge protection.

Uses

1-Bromo-2,5-dimethoxybenzene has been used in preparation of:

S-(-)-2-[N-(trifluoroacetyl)amino]-1-(2,5-dimethoxy-4- bromophenyl)-1-propanone
1,4-bis{4-[2-(4-pyridyl)ethenyl]phenyl}butadiyne and 1,4-bis{2,5-dimethoxy-4-[2-(4-pyridyl)ethenyl]phenyl}butadiyne
1-bromo-4-iodo-2,5-dimethoxybenzene

Synthesis

17332-11-5

74-88-4

25245-34-5

2-Bromo-4-methoxyphenol (13.3 g, 65 mmol) and potassium carbonate (35.9 g, 260 mmol) were suspended in dry acetone (100 mL) under nitrogen protection. Under cooling in an ice bath, iodomethane (11.1 g, 3.1 mmol) was slowly added. After addition, the reaction mixture was gradually warmed to room temperature with continuous stirring overnight. After completion of the reaction, the potassium carbonate was removed by filtration and the filtrate was concentrated under reduced pressure. The residue was purified by fast column chromatography (eluent: petroleum ether/ethyl acetate, 30:1, v/v) to afford 1-bromo-2,5-dimethoxybenzene (13.9 g, 97.9% yield) as a colorless oil.
