Reaktionsschritte
To a solution of trimethyl((3-(trifluoromethyl)phenyl)ethynyl)silane (0.500 g, 2.06 mmol) in ethanol (10 mL) was added potassium carbonate (0.253 g, 1.8 mmol) and the reaction mixture was stirred at RT for 18 h. The reaction mass was quenched in water, neutralized with dil. HCl and extracted with hexane and concentrated to afford 0.200 g of the crude product which was further purified by column chromatography using silica (60-120 mesh) eluting with pet. ether to afford 0.500 g of pure product. 1H NMR (300 MHz, DMSO d6): δ 4.41 (s, 1H), 7.64 (d, J=7.5 Hz, 1H), 7.77-7.81 (m, 3H).
