23-Sep-2021 News The origin of a common compound about 426-65-3

The synthetic route of 426-65-3 has been constantly updated, and we look forward to future research findings.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 426-65-3, name is Ethyl Pentafluoropropionate, A new synthetic method of this compound is introduced below., name: Ethyl Pentafluoropropionate

Ethyl pentafluoropropylenate (14.6 g) and hydrazine monohydrate (3.6 g) were refluxed in tetrahydrofuran (300 ml) for 1 hour. After cooling to room temperature, trifluoroacetamidine (10.0 g) was added dropwise to the mixture and it was refluxed for 3 hours. After finishing the reaction, satu- rated aqueous solution of sodium hydrogen carbonate was added thereto and the mixture was extract- ed with ethyl acetate. After drying the organic layer with anhydrous magnesium sulfate, the solvent was distilled off to obtain crude 3-pentafluoroethyl-5-trifluoromethyl-lH- (1, 2, 4)-triazole (7.9 g).

The synthetic route of 426-65-3 has been constantly updated, and we look forward to future research findings.
