Ketene O,N-acetals 3, 4, 6, 8 are obtained from N,N-diarylcarboxamides and N-acetylheterocycles 5, 7 by silylation with trimethylsilyl triflate (2) in the presence of triethylamine.Analogous reactions of carboxamides 9 and N-acyllactams 11 yield the keten

A number of substituted 2,5-bis(trimethylsiloxy)furans were prepared from the corresponding succinic anhydrides, and were found to be reactive dienes from the Diels-Alder reaction with electron-withdrawing dienophiles, giving p-quinones and hydroquinones.
