A sustainable, new synthesis of oxalamides, by acceptorless dehydrogenative coupling of ethylene glycol with amines, generating H₂, homogeneously catalyzed by a ruthenium pincer complex, is presented. The reverse hydrogenation reaction is also accomplished using the same catalyst. A plausible reaction mechanism is proposed based on stoichiometric reactions, NMR studies, X-ray crystallography as well as observation of plausible intermediates.

乙二醇和胺的无受体脱氢偶联合成和钌催化的逆氢化合成草酰胺

提出了一种可持续的，新的草酰胺的合成方法，该方法通过乙二醇与胺的无受体脱氢偶联，生成由钌夹钳络合物均匀催化的H ₂。逆氢化反应也使用相同的催化剂完成。基于化学计量反应，NMR研究，X射线晶体学以及对合理中间体的观察，提出了合理的反应机理。
