我们报道了一种复分解反应，其中来自异氰化物配体的氮宾片段与一系列铌双（亚氨基）配合物中的亚氨基配体的氮宾片段交换。这些双(亚氨基)络合物之一还促进氮宾转移，在涉及 Nb(V)/Nb(III) 氧化还原电对的过程中催化由叠氮化物和异氰化物生成不对称二烷基碳二亚胺。
We report a metathesis reaction in which a nitrene fragment from an isocyanide ligand is exchanged with a nitrene fragment of an imido ligand in a series of niobium bis(imido) complexes. One of these bis(imido) complexes also promotes nitrene transfer to catalytically generate asymmetric dialkylcarbodiimides from azides and isocyanides in a process involving the Nb(V)/Nb(III) redox couple.
