Reference of 13329-40-3,Some common heterocyclic compound, 13329-40-3, name is 1-(4-Iodophenyl)ethanone, molecular formula is C8H7IO, 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.
Example 83A 2-Bromo-1-(4-iodo-phenyl)-ethanone A solution of bromine (79.3 g, 508 mmo) in glacial acetic acid (50 mL) was added at room temperature to a solution of 1-(4-Iodo-phenyl)-ethanone (Aldrich, 125 g, 508 mmol) in glacial acetic acid (600 mL). The mixture was stirred for 10 h, then concentrated under reduced pressure and the residue was diluted with ethyl acetate (100 mL), and washed with brine (3*50 mL). The organic layer was concentrated, and the residue was crystallized from ethyl ether to provide the title compound as a yellow solid (150 g, 462 mmol, 91% yield). 1H NMR (300 MHz, CDCl3) delta 4.39 (s, 2H), 7.69 (d, J=8.5 Hz, 2H), 7.87 ppm (d, J=8.5 Hz, 2H); MS (DCl/NH3) m/z 246 (M-Br)+264 (M-Br+NH4)+.
The synthetic route of 13329-40-3 has been constantly updated, and we look forward to future research findings.
