Nitro groups on different compounds – containing double bonds, carbonyl, nitrile or halide groups – have been successfully hydrogenated with well-defined homogeneous gold and palladium complexes as catalysts using a batch reactor under low H 2 pressure. Gold complexes show high chemoselectivity towards reduction of the nitro group at near-complete conversion of the substrate. The corresponding...
The mechanism of olefin hydrogenation catalyzed by Pd II and Au III Schiff base complexes, both with an analog d 8 electronic structure, is analyzed by means of kinetic and computational methods. The computational study is able to explain the differences experimentally observed in relation to the influence of the solvent (polarity and proton donor ability) and of the hydrogen...
