Applicazioni

2,2,2-Trifluoroethyl trifluoromethanesulfonate is a powerful trifluoroethylating agent which is useful for synthesis of fluorinated amino acids. It is used as a reagent in thenantioselective preparation of cyclic N-aryl hydroxamic acids via phase-transfer catalyzed alkylation of nitrobenzyl bromides to give nirophenylalanines.

Note

Moisture sensitive. Incompatible with oxidizing agents and heat.
