Catalytic Reduction of Nitroarenes by Dipalladium Complexes: Synergistic Effect

The direct reaction between 2,7-bis(2-pyridinyl)-1,8-naphthyridine (bpnp) and Pd(CH3COO)2 in CF3COOH yields the new dinuclear palladium(II) complex [Pd2(bpnp)(μ-OH)(CF3CO2)2](CF3CO2) (1). Similarly, substitution of Pd(CH3CN)4(BF4)2 with bpnp in DMF gives [Pd2(bpnp)(μ-OH)(DMF)2](BF4)3 (2). Treatment of 1 or 2 with Cl- readily provide the chloro-substituted species [Pd(bpnp)(μ-OH)(Cl)2]+. All complexes were characterized by spectroscopic methods, and the structure of 2 was further confirmed by X-ray crystallography. Complex 1 is an efficient catalyst for the reduction of aromatic nitro compounds leading to the corresponding aniline derivatives under atmospheric pressure of hydrogen at 50 °C. The mechanistic pathway of the catalysis is investigated. From the reaction pathway, it is suggested that a facile condensation of nitroso and hydroxylamine intermediates is enabled by the dipalladium system and the desired transformation proceeds smoothly under mild reaction conditions to yield the reduced product.

Process for Alkane Oligomerization

Provided is a process for preparing oligomers from an alkane. The process comprises (a) contacting an alkane under dehydrogenation conditions in the presence of a dehydrogenation catalyst such as an iridium catalyst complex comprising iridium complexed with a benzimidiazolyl-containing ligand to form olefins, and (b) contacting the olefins prepared in step (a) under oligomerization conditions with an oligomerization catalyst such as a nickel, platinum or palladium metal catalyst complex comprising the metal complexed with a nitrogen containing bi- or tridentate ligand to prepare oligomers of the olefins, and hydrogenating the olefin oligomers. In one embodiment, the ligands of the catalyst complexes in step (a) and step (b) can be the same.
