Description

Description générale

2,2,2-Trifluoroethanol (TFE) is an organic compound with the chemical formula CF₃CH₂OH. TFE is a commonly used solvent in organic synthesis. It can also be used as a cosolvent in the experimental study of proteins and peptides.

Application

2,2,2-Trifluoroethanol can be used as a solvent:

• In the synthesis of 2-amino-3-cyano-4H-chromene and tetrahydrobenzo[b]pyran derivatives by catalyst free one-pot condensation of aldehydes, malononitrile and resorcinol or dimedone.
• In the N-formylation of amines with formic acid in the presence of heterogeneous ZIF-8 (zeolitic imidazolate framework) catalyst.
• In the preparation of 2-substituted-2,3-dihydro-4(1H)-quinazolinone derivatives by condensation of anthranilamide with alkyl, aryl, or heteroaryl ketones or aldehydes.
• In the mild and selective oxidation of sulfur compounds using H₂O₂(hydrogen peroxide).

Caractéristiques et avantages

2,2,2-Trifluoroethanol is more acidic than ethanol due to the presence of electronegative trifluoromethyl group.
