Ni3(μ3-S) bridge core. Reaction of [Ni(pdtc)CN]1− with [Fe(Me6tren)(OTf)]1+ forms the complex [Ni(pdtc)CNFe(Me6tren)]1+, the only example of a single Ni−C≡N−Fe bridge within a molecule. Structures of the various types of reaction products are presented. This work demonstrates the potential utility of bridge cleavage of polynuclear NiII thiolates, an extensive family of compounds, to produce mononuclear
Pyridine-2,6-dimethylthiolate 和pyridine-2,6- dithiocarboxylate形成微溶的 Ni II钳形配合物,配制成 [Ni(pdmt)] 2和 [Ni(pdtc)] 2,分别与两个 Ni-(μ 2 - S)-Ni 桥。在
乙腈反应系统中,后者通过一系列广泛的亲核试剂进行简单的桥裂反应 [Ni(pdtc)] 2 + 2L 0,− → 2[Ni(pdtc)L] 0,−以提供具有 L 的平面单核产物- = 卤化物、CN、Me 3 SiO -、RS -和 L 0 = Et 3 P 和N-杂环卡宾。[Ni(pdmt)] 2对桥梁破坏的反应要小得多。裂解产物支持导致其他单核物质以及双核和三核复合物的几种感兴趣的反应。[Ni(pdtc)(OSiMe 3 )] 1-使
