Article abstract of DOI:10.1055/s-1997-1501

Enamines 2 and O-trimethylsilyl ketene acetals 4 are trifluoroacetylated on reaction with the title reagent to yield trifluoroacetyl enamines 3 and trifluoromethylsilylenol ethers 5, respectively. Trifluoromethyl 1,3-diketones 6 and trifluoromethyl β-keto esters 7 are obtained by hydrolysis of compounds 3 and 5.
