On the insertion processes of unsaturated molecules into the Nb–X σ-bond of “Cp2′NbX” moieties (Cp′ = η5-C5H4SiMe3; X = H, C, P)

In this article, we have reviewed a series of insertion processes of different types of unsaturated reagents, namely carbon monoxide, carbon dioxide, isocyanates, isothiocyanates, isonitriles, alkenes and activated alkynes, in the Nb–X σ-bond, X = H, C and P, of “Cp2′NbX” moieties, Cp′ = η5-C5H4SiMe3.

Graphical abstractThe Nb–X σ-bond of the formally 16-electron moieties “Cp2′NbX” (Cp′ = η5-C5H4SiMe3; X = H, C, P) undergoes insertion processes of different types of unsaturated molecules, namely CO, CO2, isocyanates, isothiocyanates, isonitriles, olefins and activated alkynes.Figure optionsDownload full-size imageDownload as PowerPoint slide
