The use of nuclear-chemical synthesis, based on the generation of free nucleogenic phenyl cations, allowed for the direct phenylation of the nitrogen atom in 1,4-diazines. The presence of two methyl substituents in the quinoxaline substrate leads to a marked increase of diazine salt radiochemical yield. On the basis of quantum-chemical calculations the possibility of synthesizing 2,3-dimethyl-1,4-

Tritium atom distribution in the anisole formed from the attack of a nucleogenic tritiated phenyliumion on gaseous methanol provides the first experimental evidence for a gas-phase automerization of phenyliumion.

The possibility of a direct phenylation of benzoquinoline nitrogen atom with nucleogenic phenyl cations has been demonstrated. A simple method has been developed for obtaining previously unknown tritium labeled N-phenyl derivatives of benzo[h]quinolinium, which are promising radioactive markers for studying the biological action mechanisms of medicinal substances containing the benzoquinolinium structure.
