Application of 68120-35-4, Adding some certain compound to certain chemical reactions, such as: 68120-35-4, name is (3-Bromo-4-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 68120-35-4.
A mixture of (3-Bromo-4-methyl-phenyl)-methanol (8.5 g, 42.2 mmol) and bis(pinacolato)diboron (11.8 g, 46.50 mmol) in 1 ,4-dioxane (50 ml_) was degassed under N2 atmosphere for 10 min. Potassium acetate (8.2 g, 84.55 mmol) was added to the above followed by [1 ,1 – Bis(diphenylphosphino)ferrocene]dichloropalladium(ll).CH2Cl2 (1.54 g, 2.11 mmol) and the reaction mixture was heated at 100 C for 15 h. The solvents were removed under reduced pressure, the residue obtained was diluted with water and extracted with EtOAc (2×150 mL). Combined organic phases were washed with water, brine, dried over anhydrous Na2S04, filtered and concentrated. Purification of this crude by flash chromatography on silica (EtOAc:n-hexane; 70:30) afforded the title compound as a brown liquid (5.0 g, 84%). 1H NMR (400 MHz, DMSO-d6): delta 7.59 (d, J = 1.72 Hz, 1 H), 7.25 (dd, J = 7.76, 1.88 Hz, 1 H), 7.11 (d, J = 7.76 Hz, 1 H), 5.10 (t, J = 5.72 Hz, 1 H), 4.43 (d, J = 5.72 Hz, 2H), 2.42 (s, 3H), 1.29 (s, 12H).
According to the analysis of related databases, 68120-35-4, the application of this compound in the production field has become more and more popular.
