Tris(pentafluorophenyl)silyl Triflate: Synthesis and Silylation of Carbonyl Compounds. — Protodesilylation of several precursors gives the title reagent (III). It is employed in the silylation of several ketones and aldehydes such as (VI) and (VIII) to give
the corresponding silyl enol ethers in almost good yield. In contrast, silylation of esters
(XI) or (XIV) or lactones (XVI) is dependent on the reaction conditions and on the nature of the substrates. — (LEVIN, V. V.; DILMAN*, A. D.; BELYAKOV, P. A.;
