СИНТЕЗ И ПРИМЕНЕНИЕ ФОСФИНИТОВЫХ РУТЕНИЙ СОДЕРЖАЩИХ КАТАЛИЗАТОРОВ В ТРАНСФЕРНОМ ГИДРИРОВАНИИ

Трансферное гидрирование (ТГ) является весьма важной реакцией в органической химии, особенно при синтезе фармацевтических препаратов, агрохимикатов и продуктов тонкой химии. Этот метод включает перенос водорода от донорной молекулы к ненасыщенному субстрату, предлагая более безопасную и удобную альтернативу прямому гидрированию, для которого обычно требуется газообразный водород под высоким давлением, что является небезопасным. ТГ выделяется своей способностью избирательно восстанавливать несколько функциональных групп в более мягких условиях, тем самым снижая риск чрезмерного восстановления или повреждения чувствительных функциональных групп. Этот метод особенно ценен в асимметричном способе получения веществ, где хиральные катализаторы позволяют получать энантиомерно чистые соединения, имеющие решающее значение для разработки фармацевтических лекарств.

Рутениевые комплексы особенно примечательны своей эффективностью при асимметричном трансферном гидрировании. Их стабильность и адаптируемость к различным реакционным средам делают рутениевых комплексов идеальными как для лабораторного, так и для промышленного применения, они универсальны и могут использоваться для восстановления кетонов, альдегидов, иминов и нитрилов. Фосфинитовые лиганды (P(OR)R'2) используются в синтезе комплексов для улучшения их свойств. Эти лиганды очень известны своей способностью тонко настраивать электронные и стерические свойства металлоцентров. Электронодонорная природа атома фосфора в сочетании с изменчивостью функциональных групп R и R' позволяет существенно настраивать свойства катализатора.

Цель работы – обзор современных открытий в области трансферного гидрирования и исторических предпосылок ТГ.

Интеграция фосфинитных лигандов с рутениевыми катализаторами знаменует собой значительный прогресс в области трансферного гидрирования. Эти катализаторы демонстрируют повышенную эффективность, селективность и стабильность, что имеет решающее значение в асимметричном синтезе, который важен для получения фармакологических препараратов и агрохимикатов. Изучение в ходе исследования различных источников, оснований и механизмов водорода позволило глубже понять процесс TГ.
