Forbus, T. R. Jr. published the artcileReactions of the readily accessible electrophile, trifluoroacetyl triflate: a very reactive agent for trifluoroacetylations at oxygen, nitrogen, carbon, or halogen centers, Recommanded Product: N,N-Diethyl-2,2,2-trifluoroacetamide, the publication is Journal of Organic Chemistry (1987), 52(19), 4156-9, database is CAplus.
Trifluoroacetyl triflate (I) is readily prepared in 82% yield by the dehydration (P2O5) of a 2:1 mixture of CF3CO2H and CF3SO3H. Reactions of this highly electrophilic trifluoroacetylating reagent with alcs., ketones, ethers, amines, and pyridines give esters, enol esters, ether cleavage, amides, and acylpyridinium ions, resp. Reactions with ionic or easily ionizable alkyl halides give the very volatile trifluoroacetyl halides and the ionic triflate. Triphenylmethyl chloride, for example, is quant. converted to triphenylcarbenium triflate in a very convenient synthetic procedure. I is used in the synthesis of the first member of a new class of pyrylium salts, 2,6-dimethoxypyrylium triflate.
