On the contrary to the photochemical behavior the title compounds do not isomerise to a common intermediate prior to or during electron impact induced fragmentation. The unusual methyl elimination from the trans(2)-butenoic acid methyl ester probably is accompanied by a concerted [1.3] methoxy rearrangement from the ester function on to the β carbon atom.
