THE ION-MOLECULE REACTIONS OF PHENYL CATION WITH ALIPHATIC-ALCOHOLS

The efficiency of the processes of H+, H-, and H2O transfer was determ ined for multichannel ion-molecule reactions of the C6H5+ cation with molecules of ethyl and propyl alcohols. In the case of ethanol, H2O tr ansfer to phenyl cation was found to be the main process (rate constan t 2 x 10(-10) cm(3)/s). In proton transfer reactions, the process of e xcitation energy transfer from the primary ion to an alcohol molecule was found to take place. The secondary ions of [M + 1](+) type formed via proton transfer from the C6H5+ ion to ethanol and propanol molecul es undergo dissociation with H2O elimination. The efficiency of this p rocess depends on the excitation energy of phenyl cation. The [M + 2]( +) products resulting from exchange and trimolecular reactions were fo und for deuterated alcohols.
