Related Products of 171290-52-1,Some common heterocyclic compound, 171290-52-1, name is 3,5-Dimethoxyphenylacetylene, molecular formula is C10H10O2, 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.
3,5-dimethoxyphenylacetylene 81 mg (0.50 mmol), silver nitrite 154 mg (1 mmol), N-bromosuccinimide 178 mg (1 mmol)10 mL of a pressure-tight sealed container was sequentially added, and 5 mL of 1,2-dichloroethane was further added.The mixture was stirred at room temperature, and the reaction was checked by TLC. The reaction was completed in 8 hours.The reaction solution was diluted with 10 mL of dichloromethane, and filtered to give a clear liquid.Separation by column chromatography (extraction of petroleum ether/ethyl acetate in a volume ratio of 100:1)The eluate containing the desired product were collected and the solvent was evaporated to give a white solid 3,5-dimethoxy-benzonitrile 42.4mg (52% yield).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 3,5-Dimethoxyphenylacetylene, its application will become more common.
