Mander, Lewis N.,Sethi, S. Paul
, p. 5953 - 5956 (1984)
Ketones react rapidly with t-butyldimethylsilyl triflate and amine bases to form t-butyldimethylsilyl enol ethers in high yield.

A triflic imide (Tf2NH) catalyzed isomerization of kinetically favourable silyl enol ethers into thermodynamically stable ones was developed. We also demonstrated a one-pot catalytic reaction consisting of (2 + 2) cycloaddition and isomerization. In the reaction sequence, Tf2NH catalyzes both of the reactions.

N-Heterocyclic carbenes (NHCs) were found to catalyze the silyl transfer from trialkylsilyl ketene acetals to ketones. In the presence of a catalytic amount of NHC 3 (IAd, 0.1 to 5 mol%), a series of enolizable ketones as well as cyclohexanecarboxaldehyde
