Abstrakt: Appearance energy and kinetic energy release measurments together with isotopic labelling have shown that the meastable molecular ion of 1-phenylpropenol isomerizes into those of cinnamic alcohol and 3-phenylpropanal prior to loss of ketene. 13C labelling and thermodynamic considerations prove that the rearrangement of 1-phenylpropenol occurs by an ' ortho attack' leading to bicyclic intermediates. Statistical hydrogen exchanges are observed prior to fragmentation. The isomerization mechanisms are discussed. [ABSTRACT FROM AUTHOR]
