In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 3401-47-6, name is 1-Bromo-2-methoxynaphthalene belongs to ethers-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. SDS of cas: 3401-47-6
In a nitrogen filled glove box, aryl halide (0.5 mmol), if solid, boronic acid (0.75 mmol), KOH (1.0 mmol) and 4dIPr*oMe (0.005 mmol, 0.5 mol% or 0.01 mmol, 1.0 mol%) were added to a 1 dram vial equipped with a magnetic stir bar. Aryl chloride (0.5mmol), if liquid, was added by syringe, followed by THF (1 mL). The vial was sealed andstirred outside of the glove box at 80C for 12 hours. At this point, the vial was opened to air and diethyl ether (10 mL) and H20 (10 mL) were added to the reaction mixture. The aqueous phase was extracted with diethyl ether (3 x 10 mL). The combined organic phases were dried over MgSO4 and filtered. The supernatant was then passed through a pad of silica gel,followed by removal of the solvent under reduced pressure to give the organic product.?H NMR data for the following compounds were consistent with those published in Bastug & Nolan, 2014, Organometallics 33:1253-1258. Following General Procedure A, a mixture of 1-bromo-2-methoxynaphthalene (118 mg, 0.5 mmol), 2,3,5,6-tetramethylphenyl boronic acid (133 mg, 0.75 mmol), potassium hydroxide (56 mg, 1.0 mmol), 4dIPr*oMe (3.2 mg, 0.0025 mmol) and THF (1 mL) was stirred at 80C for 12 hours. The average of two runs provided a yield of 94% (136 mg).
The synthetic route of 3401-47-6 has been constantly updated, and we look forward to future research findings.
