The chemical industry reduces the impact on the environment during synthesis 21702-84-1, name is 2,4-Dibromo-1-methoxybenzene, I believe this compound will play a more active role in future production and life. 21702-84-1
53.2 g of 2,4-dibromoanisole (B30), 40.4 g of 2-methyl-3-butyn-2-ol, 3.81 g of copper iodide, 150 g of triethylamine, 75 g of tetrahydrofuran, and 14.0 g of bis ( Triphenylphosphine) palladium (II) dichloride was mixed, and the temperature was raised to 60 C and stirred for 7 hours.After cooling to room temperature, filtration was performed, and the filtrate was concentrated under reduced pressure. The obtained oily substance was purified by column chromatography [silica gel (600 g), hexane: ethyl acetate = 2: 1] to obtain 50.9 g of diol. (B31).
The chemical industry reduces the impact on the environment during synthesis 21702-84-1. I believe this compound will play a more active role in future production and life.
