Extracurricular laboratory: Synthetic route of 2′-Methoxyphenyl acetylene

According to the analysis of related databases, 2′-Methoxyphenyl acetylene, the application of this compound in the production field has become more and more popular.

767-91-9, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 767-91-9 as follows.

General procedure: A mixture of aldehyde (1.97 mmol), amine (1.97 mmol), acetylene (2.95 mmol), and thecorresponding supported Au catalyst (1% wt, 60 mg, 0.002 mmol) was heated at 60 C for 8 h,after which time the solution was cooled and the catalyst was removed by filtration. The filtrate wasevaporated under reduced pressure to afford propargylamine 5. Yields were determined by integration of the 1H-NMR spectra of the crude reaction mixtures. After separation and washing with n-pentane,the catalyst was reused intact for the next reaction without any further pre-treatment.

According to the analysis of related databases, 2′-Methoxyphenyl acetylene, the application of this compound in the production field has become more and more popular.
