✦ Synopsis

Comparisons of the mass spectral behaviour of the [M -421 ions from enol acetates and that of the corresponding ketones indicate that the elimination of a ketene molecule from enol acetates proceeded through a four-membered cyclic transition state to afford fragment ions with an enolic structure.
