摘要

Palladium nanoparticles stabilized by alkyne derivatives catalyzed the hydrogenation of nitroarenes to the aryl amines in homogeneous phase. The reaction of nitrobenzene proceeded smoothly with a substrate-to-palladium molar ratio (S/Pd) of 51,000 under 8 atm of H-2. The reaction under 1 atm of H-2 with an S/Pd of 1030 was completed in 4 h. A series of substituted nitroarenes, including 4-acetyl- and 4-formylnitrobenzenes, were converted to the aryl amines with high chemoselectivity.
