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, Application In Synthesis of (3-Bromo-2-methylphenyl)methanol, blongs to alcohols-buliding-blocks compound. Application In Synthesis of (3-Bromo-2-methylphenyl)methanol
Perbromomethane (14.35 g, 43.3 mmol) was added portionwise to a solution of (3-bromo-2-methylphenyl)methanol (7.25 g, 36.1 mmol) and triphenylphosphine (11.35 g, 43.27 mmol) in DCM (120 mL) (reaction exotherms to ?40 C.) and the reaction was stirred at room temperature for 2 hours. The residue was passed through a pad of silica, eluting with DCM. The filtrate was concentrated to dryness, then the crude product was purified by flash silica chromatography, elution gradient 0 to 25% EtOAc in heptane. Product fractions were concentrated to dryness to afford 1-bromo-3-(bromomethyl)-2-methylbenzene (8.52 g, 90%) as a colourless oil. 1H NMR (500 MHz, CDCl3, 27 C.) 2.48 (3H, s), 4.52 (2H, s), 6.99-7.05 (1H, m), 7.22-7.27 (1H, m), 7.52 (1H, dd).
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.
