Abstract
Ion-molecule reactions of a polydent nucleophile, pyridine, with tritiated phenyl cations generated by the nuclear chemical method were studied. The r esulting tritium-labeled products were identified and isolated, and the rea ction pathways were considered. The major reaction is that of phenyl cation with the heterocyclic nitrogen atom to give N-phenylpyridinium salts, In e lectrophilic attack of phenyl cations at the pyridine ring, ortho and meta substitutions prevail.
