PROCESS FOR THE PREPARATION OF TRIFLUOROACETIC ACID DERIVATIVES

摘要

Good yields of trifluoroacetyl compounds, particularly trifluoroacetyl chloride, with short reaction times, are obtained by reaction of 1,1,1 trifluoro-2,2,2 trichloroethane with sulfur trioxide, in presence of mercury salts and addition of boron halide and/or halogenated sulphonic acid.
