间接CO2氢化：报告了尿素衍生物氢化为相应的胺和甲醇（见图）。该反应由基于联吡啶的三齿PNN Ru（II）钳形络合物催化，并在温和的中性条件下使用13.6 atm的H2进行。由于尿素衍生物可从CO2中获得，因此为CO2间接加氢制甲醇提供了温和的方法。
Indirect CO2 hydrogenation: Hydrogenation of urea derivatives to the corresponding amines and methanol is reported (see picture). The reaction is catalyzed by a bipyridine‐based tridentate PNN Ru (II) pincer complex and proceeds under mild, neutral conditions using 13.6 atm of H2. A mild approach is offered for the indirect hydrogenation of CO2 to methanol as urea derivatives are available from CO2.
