Related Products of 40400-15-5,Some common heterocyclic compound, 40400-15-5, name is 2-(2-Iodophenyl)acetonitrile, molecular formula is C8H6IN, 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.
Under a protective atmosphere of inert gas, Pd(OAc)2 (2.2 mg, 10 mol%), XPhos (19.1 mg, 20 mol%), NBE-CO2K (3.5 mg, were added to a 4.0 mL reaction flask equipped with a magnetic stir bar. 10 mol%), 2-(2-iodophenyl)acetonitrile (0.2 mmol, 1.0 equiv.), ethylene oxide (0.6 mmol, 3.0 equiv.) and dry N-methylpyrrolidone(1.0 mL). The reaction flask was capped and stirred at room temperature for about 5 minutes, after which the mixture was heated to 80 C and stirred for 24 hours.After the reaction vessel was cooled to room temperature, it was quenched with water (10 mL), extracted with methyl tert-butyl ether (3×10 mL), dried over Na2SO4Filter and concentrate under vacuum. Purified by column chromatography, the eluent was petroleum ether: ethyl acetate = 20:1 (v/v).There was obtained 26 mg of 2-(2,3-dihydrobenzofuran-7-yl)acetonitrile (colorless oily liquid, yield 82%).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 2-(2-Iodophenyl)acetonitrile, its application will become more common.
