An efficient visible-light-induced iron-catalyzed reduction of nitroarenes to anilines by using N-ethylmorpholine (NEM) as a reductant under mild conditions has been developed. The reaction proceeds with photosensitizer-free and features good excellent yields broad functional group tolerance. Preliminary mechanistic investigations showed that this was conducted via ligand-to-metal (NEM Fe3+) charge transfer nitro triplet biradical-induced hydrogen atom processes.

Abstract Anilines are a common motif in many bioactive compounds and their production through the reduction of nitroarenes has become an essential method for synthesis. We demonstrate that combination amine-borane complex hypoboric acid (tetrahydroxydiborane) under visible light irradiation can accomplish to corresponding anilines. Preliminary mechanistic studies suggest generation boryl radicals via hydrogen atom transfer (HAT) step from photoexcited nitroarene. Involvement parallel thermal pathway is demonstrated with high reaction efficiency being partially attributed both routes.

Abstract Reducing nitro compounds to amines is a fundamental reaction in producing valuable chemicals industry. Herein, the synthesis and characterization of zirconium metal‐organic framework‐supported salicylaldimine‐cobalt(II) chloride (salim‐UiO‐CoCl) its application catalytic reduction are reported. Salim‐UiO‐Co displayed excellent activity chemoselective aromatic aliphatic corresponding presence phenylsilane as reducing agent under mild conditions. catalyzed had broad substrate scope with tolerance diverse functional groups, including easily reducible ones such aldehyde, keto, nitrile, alkene. MOF catalyst could be recycled reused at least 14 times without noticeable losing selectivity. Density theory (DFT) studies along spectroscopic analysis were employed get into comprehensive investigation mechanism. This work underscores significance MOF‐supported single‐site base‐metal catalysts for sustainable cost‐effective chemical feedstocks fine chemicals.
