Application of 2142-70-3, These common heterocyclic compound, 2142-70-3, name is 1-(2-Iodophenyl)ethanone, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
[283] To a solution of 1-(2-iodophenyl)ethanone (4.0 g, 16.3 mmol) in a mixed solvent of chloroform (50 mL) and ethyl acetate (50 mL) was added cupric bromide (7.26 g, 32.5 mmol). The resulted mixture was stirred at reflux for 3h, then cooled down to roomtemperature, filtered, the filter cake was washed with ethyl acetate (50 mL), the filtrate was concentrated, the residue was purified by flash chromatography (petroleum ether: ethyl acetate= 50:1) to afford 2-bromo-1-(2-iodophenyl) ethanone (4.65 g, yield: 88%) as a light yellow oil.[284] ?H NIVIR (400 IVIFIz, CDC13-d): 7.98 (d, J = 8.0 Hz, 1H), 7.47 (d, J = 8.0 Hz, 2H), 7.19-7.21 (m, 1 H), 4.47 (s, 2H).
The synthetic route of 2142-70-3 has been constantly updated, and we look forward to future research findings.
