AbstractThe ion–molecule reactions of allyl bromide with the molecular ion of allyl bromide and with its major fragment, the allyl ion, yield the C6H7+ and C6H9+ ions. The structure of these product ions was explored by means of photofragmentation with laser light in the 10 μm region and by proton transfer reaction to selected reagents. These product ions were also formed by other reactions and their reactivities compared. In both cases the presence of at least two populations is demonstrated. For C6H9+ these two populations are initially present, whereas for C6H7+ an isomer is formed by the infrared light before the loss of H2. When this ion is produced by photofragmentation of C6H7+, at least one third, stable isomer is formed. Two isomers of C6H5+ are formed in the photofragmentation of C6H7+, but only one form photofragments further by loss of C2H2. The use of non‐linear least‐squares fitting does not allow definite conclusions to be drawn concerning the kinetics of the consecutive photofragmentations.

the corresponding alkenes in fair to good yields via telluroxide elimination. The MCPBA or air oxidation of some allylic ferrocenyl tellurides in ethanol produced the corresponding allylic alcohols via [2,3] sigmatropic rearrangement. 1H NMR and electronic absorption spectroscopic studies revealed that donor-acceptor complexes between alkyl ferrocenyl tellurides and TCNE were produced, an improvement
