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. 10602-03-6, name is Ethyl 4-ethynylbenzoate, This compound has unique chemical properties. The synthetic route is as follows., Product Details of 10602-03-6
General procedure: n-BuLi (4.70mL, 1.6M in hexane, 7.57mmol, 1.0equiv) was added dropwise to a solution of acetylene (7.57mmol, 1.0equiv) in 7.6mL of dry THF at -78C under a nitrogen atmosphere. After 60min at this temperature, trimethylborate (1.10g, 11.3mmol, 1.5equiv) was added dropwise at -30C. The mixture was stirred at this temperature for 60min and slowly allowed to warm to room temperature within another 60min. A saturated 4.5M aqueous solution of potassium hydrogen difluoride (KHF2) (10.1mL, 45.3mmol, 6.0equiv) was added at -20C to the vigorously stirred solution. The resulting mixture was continued to stir for 60min at -20C after which it was allowed to warm to room temperature for 60min. The solvent was removed under reduced pressure, and the resulting white solid was dried under high vacuum to remove water. The solid was washed first with acetone and then with hot acetone. The solution was concentrated to afford a white solid. The solid was dissolved in minimum amount of hot acetone, precipitated by adding methyl tert-butyl ether (MTBE), after which the solution was cooled to -20C to complete precipitation of the solid. The product was collected as an off white solid 2a-o in 40-80% yield.
According to the analysis of related databases, 10602-03-6, the application of this compound in the production field has become more and more popular.
