Catalytic hydrogenation under mild conditions of olefins, unsaturated aldeydes and ketones, nitriles and nitroarenes was investigated, using a supported rhodium complex obtained by copolymerization of Rh(cod)(aaema) [cod: 1,5-cyclooctadiene, aaema-: deprotonated form of 2-(acetoacetoxy)ethyl methacrylate] with acrylamides. In particular, the hydrogenation reaction of halonitroarenes was carried out under 20 bar hydrogen pressure with ethanol as solvent at room temperature, in order to minimize hydro-dehalogenation. The yields in haloanilines ranged from 85% (bromoaniline) to 98% (chloroaniline).
研究了通过 Rh(cod)(aaema)[cod：1,5-环辛二烯，aaema-：丙烯酸 2-(乙酰乙酰氧基)乙酯的去质子形式]与丙烯酰胺共聚得到的负载型铑配合物在温和条件下对烯烃、不饱和醛和酮、腈和硝基芳烃的催化氢化反应。特别是，在 20 巴氢气压力下，以乙醇为溶剂，在室温下进行卤代硝基芳烃的氢化反应，以尽量减少氢脱卤反应。卤苯胺的收率范围从 85%（溴苯胺）到 98%（氯苯胺）。
