Abstract

Способ получения промежуточных соединений N-алифатического замещенного п-фенилендиамина осуществляют путем контактирования алифатического амина, циклоалифатического амина или гетероциклического амина и нитробензола в присутствии подходящего растворителя, который представляет собой нейтральный или основный органический растворитель, взаимодействия указанного амина и нитробензола в присутствии гидроксида тетраалкиламмония и такого количества протонного материала, которое меньше количества, приводящего к замедлению реакции амина с нитробензолом, при температуре 20-100°C.
