Applications

1-Bromo-3,3,3-trifluoroacetone is used in the preparation of 3-nonylthio-1,1,1-trifluoropropan-2-one and perfluoroalkylated trans-allylic alcohols. It is involved in the synthesis of cyclic tetrapeptides. Further, it reacts with potassium enolate of ethyl 4,4,4-trifluoroacetoacetate to produce ethyl 2,4-bis(trifluoromethyl)-4-hydroxydihydro-3-furoate.

Notes

Incompatible with strong oxidizing agents and bases.

The oxime is readily converted with base to the highly reactive species 1,1,1-trifluoro-2-nitroso-2-propene, which undergoes hetero-Diels-Alder reactions, e.g. with cyclopentadiene or indole to give fused oxazolines. The indole adduct rearomatizes to give 1-(3-indolyl)-3,3,3-trifluoroacetoxime: J. Org. Chem., 57, 339 (1992).
