Application 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 mixture of (2-methyl-3 -(4,4,5,5 -tetramethyl- 1,3 ,2-dioxaborolan-2-yl)phenyl)methanol (1.728 g, 6,96 mmol), (3-bromo-2-methylphenyl)methanol (1.40 g, 6.96 mmol), Pd(dppf)C12CH2C12(0.5 09 g, 0.696 mmol) and potassium carbonate (1.922 g, 13.93 mmol) under N2 was added a mixture of solvents (20 mL dioxane and 5 mL water) and heated to 85 C in a heating block for 2h, at which time all SM was consumed by LCMS. After cooling to room temperature, the reaction was diluted with EtOAc and water. The organic layer was separated, dried with Na2504 and concentrated. Purified by silica gel chromatography (eluting with EtOAc-Hex) to provide (2,2?-dimethyl-[1,1?-biphenylj-3,3?-diyl)dimethanol as a light oil that crystallized on standing. [M-OHj = 225. ?H NMR (400 MI-Tz, DMSO-d6) 7.37 (dd, J = 7.6, 1.3 Hz, 2H), 7.19 (t, J = 7.5 Hz, 2H), 6.92 (dd, J = 7.6, 1.4 Hz, 2H), 5.10 (t, J = 5.4 Hz, 2H), 4.52 (d, J = 5.4 Hz, 4H), 1.88 (s, 6H).
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.
