由炔衍生物稳定的钯纳米颗粒在均相中催化硝基芳烃氢化成芳基胺。在8 atm H-2 下，硝基苯的反应顺利进行，底物与钯的摩尔比（S/Pd）为51,000。在S/Pd为1030的1atm H-2下反应在4小时内完成。一系列取代的硝基芳烃，包括4-乙酰基-和4-甲酰基硝基苯，被转化为具有高化学选择性的芳基胺。 (C) 2015 Elsevier Ltd. 保留所有权利。
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. (C) 2015 Elsevier Ltd. All rights reserved.
