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.

The elimination of acetic acid from the MH(+) ions of acetates of stereoisomeric 2-methyl-1-cyclohexanols and 1-hydroxy-trans-decalins exhibits a significant degree of stereospecificity under isobutane chemical ionization and collision-induced dissociation (CID) conditions, resulting in more abundan
