Abstract:
Production of anilines—key intermediates for the fine chemical, agrochemical, and pharmaceutical
industries—relies on precious metal catalysts that selectively hydrogenate aryl nitro groups in
the presence of other easily reducible functionalities. Herein, we report convenient and stable iron
oxide (Fe2O3)–based catalysts as a more earth-abundant alternative for this transformation.
Pyrolysis of iron-phenanthroline complexes on carbon furnishes a unique structure in which
the active Fe2O3 particles are surrounded by a nitrogen-doped carbon layer. Highly selective
hydrogenation of numerous structurally diverse nitroarenes (more than 80 examples) proceeded in
good to excellent yield under industrially viable conditions.
