A study of ion-molecular reactions of fluoro-substituted phenyl cations with benzopyridine derivatives demonstrated the following: (a) at present only the nuclear-chemical method enables the reaction of a direct phenylation of the nitrogen atom in benzopyridine derivatives, which makes it possible to obtain previously unknown quaternized structures, and (b) generation of nucleogenic phenyl cations with various substituents leads to a simultaneous introduction of the required substituents into the aromatic ring at the nitrogen heteroatom. Quantum-chemical calculations additionally confirmed the assumption about the pathways of the ion-molecular reactions with nucleogenic phenyl cations.

氟取代的成核苯基阳离子与苯并吡啶衍生物的反应研究

对氟取代的苯基阳离子与苯并吡啶衍生物的离子分子反应的研究表明：（a）目前，只有核化学方法才能使苯并吡啶衍生物中的氮原子直接苯基化，这使其成为可能为了获得先前未知的季铵化结构，和（b）产生具有各种取代基的生核苯基阳离子导致将所需的取代基同时引入到氮杂原子处的芳环中。量子化学计算还证实了有关与核型苯基阳离子发生离子分子反应的途径的假设。
