Application
Rifluoroacetaldehyde Ethyl Hemiacetal: A Precursor of Trifluoromethyl Compounds
Trifluoroacetaldehyde ethyl hemiacetal is used for preparation of trifluoromethyl compounds such as β-hydroxy-β-trifluoromethyl ketones, α-trifluoromethyl alcohols and α-trifluoromethyl amines.1-3) It is also used for in situ generation of gaseous unstable trifluoroacetaldehyde (b.p. -18 °C) in organic synthesis.4-6)
