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
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。
