Adding a certain compound to certain chemical reactions, such as: 83647-43-2, (3-Bromo-2-methylphenyl)methanol, 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, Computed Properties of C8H9BrO, blongs to alcohols-buliding-blocks compound. Computed Properties of C8H9BrO
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 title compound. 1H-NMR (500 MHz, CDCI3) 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).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,83647-43-2, (3-Bromo-2-methylphenyl)methanol, and friends who are interested can also refer to it.
