REACTIONS OF TOLUENE MOLECULAR ION WITH MOLECULES OF AROMATIC-COMPOUNDS

The kinetics of ion-molecule reactions of proton transfer from the mol ecular ion of toluene to thiophene, acetophenone, benzaldehyde, and py ridine molecules is studied. The transfer is shown to proceed via an i ntermediate complex, whose formation is associated with overcoming the activation barrier at the expense of internal and kinetic energies of the primary ions. The analysis of the data obtained shows that the re action rate constant increases exponentially with increasing proton af finity for both aromatic compounds and aliphatic ketones and alcohols studied previously.
