TLDR
The Fe4S4(SPh)42-42 cluster, in MeCN or MeCN-MeOH (1:1) containing t-butyl thiol and Et3N, catalyses the reduction of nitrobenzene and m-dinitrobenzinene to aniline and n-nitroaniline, respectively, with concomitant oxidation of the terminal ligand of the Fe 4S4 cluster to t -butyl phenyl disulphide, and then di-t-Butyl disULphideAbstract:

Reduction of Nitro and Nitroso Compounds
TL;DR: Aromatic nitro compounds are the usual starting materials for commercial applications, but aliphatic compounds exhibit a greater diversity of chemical behavior under reducing conditions as mentioned in this paper, and are frequently encountered during the reduction of Nitro compounds, such as hydroxylamines, oximes, amines, nitrones, ketones and silyl nitronates.

Selective Synthesis of Site-Differentiated Fe4S4 and Fe6S6 Clusters
TL;DR: A new family of tridentate imidazolin-2-imine ligands L(NImR)3 that can bind [Fe4S4]2+ or [Fe6S6]3+ clusters, depending on the steric profile of the ligand and the reaction stoichiometry is reported.

Catalytic transfer hydrogenation of aromatic nitro compounds in the presence of nickel thiolato-complexes
Anna Vizi-Orosz,László Markó +1 more
TL;DR: In this paper, the transfer hydrogenation of aromatic nitro compounds by hydrazine to corresponding anilines is catalyzed by (Bu4N)[Ni(tdt)2] (tdt=toluene-3,4-dithiolate) and analogous NiIII complexes in refluxing THF; hydroxylamine derivatives are formed as intermediates.
