Related Products of 83647-43-2, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 83647-43-2, name is (3-Bromo-2-methylphenyl)methanol. This compound has unique chemical properties. The synthetic route is as follows.
To a flask charged with (3-bromo-2-methylphenyl)methanol (6.0 g, 30 mmol) was added a 1M TFA solution of Thallium Trifluoroacetate (16.2 g, 29.8 mmol). The mixture was stirred at RT overnight. Analysis by TLC showed no starting material remaining. The solvent was removed under vacuum, and the residue was pumped under high vacuum for 30 min to ensure complete removal of TFA. To the residue was then added Palladium(II) Chloride (529 mg, 2.98 mmol), Lithium Chloride (2.53 g, 59.7 mmol), Magnesium Oxide (2.41 g, 59.7 mmol), and MeOH (150 mL). The reaction was flushed with CO twice, and kept under CO at room temperature. Analysis by LC showed a big product spot within 2 hours. To this solution was added ethyl acetate to precipitate the salts. The black solution was filtered through a celite pad, washed with EtOAc, adsorbed onto silica and purified by silica gel chromatography to afford 5-bromo-4-methyl-2-benzofuran-1(3H)-one. 1H-NMR (500 MHz, CDCl3) delta ppm 7.71 (d, J = 8.0 Hz, 1H), 7.58 (d, J = 8.0 Hz, 1H), 5.25 (s, 2H), 2.37 (s, 3H).
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 83647-43-2, (3-Bromo-2-methylphenyl)methanol.
