Abstract
Ion-molecule reactions of free phenyl cations generated by β-decay of tritium incorporated in labeled benzene with various pyridine derivatives were studied. The effect of electron-donor (methyl groups) and electron-acceptor (bromine) substituents in the heterocyclic ring on the course of electrophilic addition and electrophilic substitution was studied. The one-step nuclear-chemical synthesis yielded N-phenyl quaternary salts of methyl and bromo derivatives of pyridine and quinoline, labeled with tritium.
