4-Dimethylamino-1-trifluoroacetylpyridinium Trifluoroacetat: An Efficient Reagent for the Preparation of Trifluoromethyl-1,3-Dicarbonyl CompoundsEnamines 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.

trifluoroacetyl enamines - trifluoromethyl-silyl-enol ethers - trifluoromethyl-1,3-diketones - trifluoromethyl β-oxo esters - trifluoroacetylation
