Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 171290-52-1, name is 3,5-Dimethoxyphenylacetylene, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 171290-52-1
General procedure: 2-Iodo-N-phenyl-N-(trimethylsilylethynyl)benzenesulfonamide 18 (100 mg, 0.22 mmol), CuI (4.2 mg, 0.022 mmol), and PdCl2(PPh3)2 (7.7 mg, 0.011 mmol) were placed successively in a two-necked 100 mL flask containing a bar magnet and capped by a three-way stopcock. The reactor was purged of air (three vacuum-nitrogen cycles) before 5 mL of dry and degassed triethylamine and 3 mL of dry and degassed THF were added. 0.5 h later, the desired alkyne 19 (0.24 mmol) was added. The resulting mixture was stirred at room temperature and the reaction was followed by thin layer chromatography. When the reaction was complete, the solvents were removed under reduced pressure and the crude product was purified by column chromatography.
According to the analysis of related databases, 171290-52-1, the application of this compound in the production field has become more and more popular.
