   <abstract xml:lang="ru">
    <p>Исследовано нитрование 4-хлор-3-нитробензойной кислоты. Субстрат является сильно дезактивированным для реакций SEAr, и требуются жесткие условия для их проведения (безводный KNO3 в концентрированной H2SO4 при 165 °С в течение 10 часов). Разработаны методики превращения 4-хлор-3,5-динитробензойной кислоты и её сложного эфира в новые полициклические системы, содержащие пиридиновый или пиперидиновый фрагменты в реакциях кватернизации и восстановления.</p>

    <p>This article deals with the study of the nitration of 4-chloro-3-nitrobenzoic acid. The substrate is highly deactivated for SEAr reactions and therefore strict conditions are required (anhydrous KNO3 in concentrated H2SO4 at 165 °C for 10 hours). We have developed methods for the transformation of 4-chloro-3,5-dinitrobenzoic acid and its ester into new polycyclic systems containing pyridine or piperidine fragments by quaternization and reduction reactions.</p>
