Fe₃O₄ Nanoparticles: A Conveniently Reusable Catalyst for the Reduction of Nitroarenes Using Hydrazine Hydrate

Abstract

A magnetic personality: Commercially available Fe3O4 nanoparticles were utilized for efficient nitroarene reductions, and could be recycled up to 10 times using magnetic separation, whilst retaining activity (99 % aniline yield in each case without any side-products). Excellent chemoselectivity for reduction of the nitro versus other functional groups, such as halogen, ester, O-benzyl, and N-Cbz groups, was observed.
