Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 33070-32-5, name is 5-Bromo-2,2-difluorobenzodioxole, This compound has unique chemical properties. The synthetic route is as follows., Quality Control of 5-Bromo-2,2-difluorobenzodioxole
General procedure: Method A. A solution of Pd(OAc)2 (25.2 mg, 0.112 mmol) and triphenylphosphine (147 mg, 0.560 mmol) in absolute ethanol (4 mL) and anhydrous toluene (4 mL) was stirred at RT under nitrogen for 10 min. After that period, commercially available 5-chloro-2-nitrotoluene 4 (646 mg, 3.76 mmol), 4 mL of 2M aqueous Na2CO3, and the appropriate boronic acid R1B(OH)2 (6.03 mmol) were sequentially added. The resulting mixture was heated at 100 C in a sealed vial under nitrogen overnight. After being cooled to RT, the mixture was diluted with water and extracted with EtOAc. The combined organic phase were dried and concentrated. The crude product was purified by flash chromatography over silica gel column using n-Hex/EtOAc or CHCl3/MeOH mixtures as the eluent.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 33070-32-5.
