The complexation of di-(2-pyridylmethyl)amine to RuHCl(PPh(3))(3) affords the salt [RuH{κ(3)N-fac-1,3-di-(2-pyridylmethyl)amine}(PPh(3))(2)]Cl. Reaction with potassium tert-butoxide at room temperature yields the unusual ruthenaziridine complex RuH{κ(3)C(alk)NN(py)-1,3-di-(2-pyridylmethyl)amine}(PPh(3))(2), where the central nitrogen atom, adjacent alkyl carbon, and pyridine arm coordinate to the metal, leaving the second pyridine arm uncoordinated. Surprisingly, heating of this ruthenaziridine complex with concomitant H(2) formation affords the ruthenium azaallyl complex RuH(κ(3)N-1,3-di-(2-pyridyl)-2-azaallyl)(PPh(3))(2). This is a rare example of a 4d metal complex containing the azaallyl ligand. X-Ray crystal structures and NMR characterization of all three compounds are presented herein.
二（2-吡啶甲基）胺与 RuHCl(PPh(3))(3) 的络合作用提供了盐 [RuH{κ(3)N-fac-1,3-二-(2-吡啶甲基)胺}(PPh(3))(2)]Cl。在室温下与叔丁醇钾反应生成了不寻常的钌氮杂环丙烷络合物 RuH{κ(3)C(alk)NN(py)-1,3-二-(2-吡啶甲基)胺}(PPh(3))(2)，其中中心氮原子、相邻的烷基碳和吡啶臂与金属配位，留下第二个吡啶臂未配位。令人惊讶的是，加热该钌氮杂环丙烷配合物并伴随着 H(2)的形成，得到了钌氮杂烯丙基配合物 RuH(κ(3)N-1,3-二-(2-吡啶基)-2-氮杂烯丙基)(PPh(3))(2)。这是一个罕见的含有氮杂烯丙基配体的 4d 金属配合物的例子。本文介绍了所有三种化合物的 X 射线晶体结构和 NMR 表征。
