Reference of 83647-43-2, Adding some certain compound to certain chemical reactions, such as: 83647-43-2, name is (3-Bromo-2-methylphenyl)methanol,molecular formula is C8H9BrO, 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 83647-43-2.
To a flask charged with (3-bromo-2-methylphenyl)methanol (6.0 g, 30 mmol) was added a 1M trifluoroacetic acid solution of thallium trifluoroacetate (16.2 g, 29.8 mmol). The mixture was stirred at RT overnight. The solvent was removed under vacuum, and the residue was pumped under high vacuum for 30 minutes 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 methanol (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-l(3H)-one. ?-NMR (500 MHz, CDC13) 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).
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. 83647-43-2, (3-Bromo-2-methylphenyl)methanol, other downstream synthetic routes, hurry up and to see.
