A cobalt–rhodium heterobimetallic nanoparticle (Co₂Rh₂/C)-catalyzed tandem reductive amination of aldehydes with nitroaromatics to sec-amines has been developed. The tandem reaction proceeds without any additives under mild conditions (1 atm H₂ and 25 °C). This procedure can be scaled up to the gram scale, and the catalyst can be reused more than six times without loss of activity.

大气氢气氛下双金属钴铑纳米颗粒催化的硝基芳烃与醛的还原胺化

已经开发了钴铑异双金属纳米颗粒（Co ₂ Rh ₂ / C）催化的醛与硝基芳烃串联还原为氨基胺。在温和条件下（1 atm H ₂和25°C），串联反应在没有任何添加剂的情况下进行。该程序可以放大到克级，并且催化剂可以重复使用六次以上，而不会损失活性。
