Aplicaciones

Ethyl trifluoroacetate is used as an intermediate in organic synthesis to prepare organic fluorine compounds like 3-ethyl-1-methylimidazolium trifluoroacetate (EMITA). It is involved in the syntheses of various pharmaceutically active molecules and agricultural products. It is also useful for the preparation of tri fluoroacylated compounds.

Notas

Moisture Sensitive. Keep the container tightly closed in a dry and well-ventilated place. Incompatible with strong oxidizing agents, strong bases and strong acids.

Reagent for selective trifluoroacetylation of amines. Primary amines can be protected in the presence of secondary, and diamines selectively monoprotected. Primary amines can also be differentiated in terms of steric hindrance: Tetrahedron Lett., 36, 7357 (1995).

Esters of perfluoroalkyl carboxylic acids undergo Wittig reactions, for example with the ylide from (3-Phenyl­propyl)­triphenyl­phosphonium bromide, A12669, leading to 1-perfluoroalkyl enol ethers, which are useful precursors of various fluorinated derivatives: J.
