General and Selective Iron-Catalyzed Transfer Hydrogenation of Nitroarenes Without Base. -Transfer reduction of the industrially relevant nitroarenes to the corresponding anilines is developed. The reaction is not sensitive to electronic or steric effects in the substrates. -(WIENHOEFER, G.; SORRIBES, I.; BODDIEN, A.; WESTERHAUS, F.; JUNGE, K.; JUNGE, H.; LLUSAR, R.; BELLER*, M.; J. Am. Chem. Soc. 133 (2011) 32, 12875-12879, http://dx.
Catalyst. -The scalable reaction procedure tolerates a wide variety of functional groups including reducible ones. The catalyst is recycled and reused in four additional cycles with gradually decreasing reactivity. -(WESTERHAUS, F. A.; SORRIBES, I.; WIENHOEFER, G.; JUNGE, K.; BELLER*, M.; Synlett 26 (2015) 3, 313-317, http://dx.
Hydrogenation of Nitroarenes Using Defined Iron-Phosphine Catalysts. -A novel, highly chemoselective hydrogenation of nitroarenes to corresponding amines (18 examples) is developed. -(WIENHOEFER, G.; BASEDA-KRUEGER, M.; ZIEBART, C.; WESTERHAUS, F. A.; BAUMANN, W.; JACKSTELL, R.; JUNGE, K.; BELLER*, M.; Chem. Commun. (Cambridge) 49 (2013) 80, 9089-9091, http://dx.
An improved method is presented for the Ru-catalyzed hydrogen peroxide oxidation of naphthalenes, naphthols and phenols to the corresponding quinones. Excellent regioselectivities (50:1 and higher) are achieved. The presence of alkyl groups is beneficial for high yields. -(WIENHOEFER, G.; SCHROEDER, K.; MOELLER, K.; JUNGE, K.; BELLER*, M.; Adv.

Selective Hydrogenation of Alkynes Catalyzed by Trinuclear Rhodium Hydride Complexes of the Type [{(Rh[PP*]H)3(μ2-H)3(μ3-H)}(BF4)2]. -(KOHRT, C.; WIENHOEFER, G.; PRIBBENOW, C.; BELLER, M.; HELLER*, D.; ChemCatChem 5 (2013) 10, 2818-2821, http://dx.
Chemoselective Transfer Hydrogenation to Nitroarenes Mediated by Cubane--Type Mo3S4 Cluster Catalysts. -A wide range of aromatic and heteroaromatic nitro-compounds is reduced to the corresponding amines using formates as reducing agent. High functional group tolerance is shown. -(SORRIBES, I.; WIENHOEFER, G.; VICENT, C.; JUNGE, K.; LLUSAR, R.; BELLER*, M.; Angew. Chem., Int.
