4923-87-9, 5-Bromobenzothiophene is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

A solution of 5-bromo-1-benzothiophene (2 g, 9.385 mmol), phenylboronic acid (1.2 g, 9.841 mmol), Pd(PPh3)4, (544 g, 0.471 mmol), potassium carbonate (1.9 g, 13.747 mmol) in toluene and water (20+20 mL) mixture was refluxed at 100C for overnight. After completion of the reaction, the mixture was cooled to room temperature, diluted with ethyl acetate, filtered through a Celite bed, and washed with ethyl acetate. The combined filtrate was washed with water and brine. The organic layer was dried over sodium sulfate and concentrate under reduced pressure to give residue which was purified by column chromatography using hexane as eluent on silica gel to afford 5-phenyl-1-benzothiophene (1.7 g, 8.084 mmol, 86%) as white solid. ?H-NMR (400 MHz, CDC13): oe 7.95 (d, J=l.5 Hz, 1H), 7.86 (dd, J?=8.5 Hz, J?0.7 Hz, 1H), 7.60-7.58 (m, 2H), 7.52 (dd, J?=8.3 Hz, J?=1.7 Hz, 1H), 7.41-7.37 (m, 3H), 7.32-7.27 (m, 2H).

4923-87-9 5-Bromobenzothiophene 2776578, abenzothiophene compound, is more and more widely used in various.
