Adding a certain compound to certain chemical reactions, such as: 7252-83-7, name is 2-Bromo-1,1-dimethoxyethane, belongs to ethers-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 7252-83-7, Application In Synthesis of 2-Bromo-1,1-dimethoxyethane
Dissolve 4-fluorophenol (5.5 g, 49.1 mmol) in acetonitrile (49 mL) and treat the solution with 2-bromo-l, l-dimethoxy ethane (11.6 mL, 98.1 mmol) and K2CO3 (16.95 g, 122.7 mmol). Heat the solution to reflux with stirring for five days. Filter the mixture, and concentrate the filtrate under reduced pressure. Subject the resulting crude material to silica gel chromatography eluting with a gradient of 0% to 50% EtOAc/hexanes. Concentrate the fractions containing the desired product under reduced pressure to furnish the title compound as a colorless oil (5.85 g, 60% yield). Mass spectrum (m/z) 218 (M + NH4)+, 223 (M + Na)+.
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-1,1-dimethoxyethane, other downstream synthetic routes, hurry up and to see.
