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 [Pd-2(bpnp)(mu-OH)(CF3CO2)(2)](CF3CO2) (1). Similarly, substitution of Pd(CH3CN)(4)(BF4)(2) with bpnp in DMF gives [Pd-2(bpnp)(mu-OH)(DMF)(2)](BF4)(3) (2). Treatment of 1 or 2 with Cl- readily provide the chloro-substituted species [Pd(bpnp)(mu-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 degrees 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.
