Category: 76008-73-6

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. 76008-73-6, name is Ethyl 5-bromo-2-chlorobenzoate, This compound has unique chemical properties. The synthetic route is as follows., Formula: C9H8BrClO2

Under a nitrogen atmosphere, a 50 mL round bottom flask is charged with bis(pinacolato)diborane (1.16 g, 4.55 mmol), potassium acetate (1.11 g, 11.4 mmol) and 5-bromo-2- chloro-benzoic acid ethyl ester (1 g, 3.79 mmol). After bubbling nitrogen through the mixture for 5 minutes, dichloro[l,r-bis(diphenylphosphino)ferrocene]palladium DCM adduct [PdCl2(dppf), 93 mg, 0.11 mmol] is added. The resulting mixture is heated to 60C for 2 hours, cooled to room temperature and poured into EtOAc (50 mL). This mixture is washed with water, with brine, dried over sodium sulfate, filtered and concentrated to give 2-chloro-5-(4A5,5-tetramethyl-[l . 3,2″|dioxaborolan-2-yl)- benzoic acid ethyl ester [LCMS: Rtau = 5.1 minutes, MS: 311 (M+H)] and the dimerized side product, 4,3′-Dichloro-biphenyl-3,4′-dicarboxylic acid diethyl ester in 2:1 ratio (0.65 g total). The crude mixture is used for a next step without further purification.

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 76008-73-6.
