Hydrogenation of amides in the presence of [Ru(acac)3] (acacH=2,4‐pentanedione), triphos [1,1,1‐tris‐ (diphenylphosphinomethyl)ethane] and methanesulfonic acid (MSA) produces secondary and tertiary amines with selectivities as high as 93 % provided that there is at least one aromatic ring on N. The system is also active for the synthesis of primary amines. In an attempt to probe the role of MSA and
在[Ru(acac)3 ](acacH = 2,4-戊二酮),三[[1,1,1-三(二苯基膦甲基)乙烷]]和甲磺酸(MSA)的存在下进行酰胺加氢生成仲胺和叔胺如果在N上至少有一个芳环,则其选择性高达93%。该系统对伯胺的合成也具有活性。为了探索MSA的作用和反应机理,已经从[Ru(acac)3 ],三醇和MSA或[RuX(OAc)(triphos)]的反应中制备了一系列甲磺酸钠络合物。 (X = H或OAc)或[RuH 2(CO)(triphos )]与MSA。晶体学表征复合物包括:[茹(OAC-κ 1 O)2(H 2O)(triphos)],[Ru(OAc‐κ 2 O,O')(CH 3 SO 3 ‐κ 1 O)(triphos )],[Ru(CH 3 SO 3‐ κ 1 O)2(H 2 O)(三膦)]和[孺2(μ-CH 3 SO 3)3(三磷酸)2 ] [CH 3 SO 3 ],而其他复合物,例如[茹(OAC-κ
