Low-valent early transition metals are often intrinsically highly reactive as a result of their
strong propensity toward oxidation to more stable high-valent states. Harnessing these …

While β-diketiminate (BDI or 'nacnac') ligands have been widely adopted to stabilize a wide
range of metal ions in multiple oxidation states and coordination numbers, in several …

β-Diketiminate (BDI) ligands are widely used supporting ligands in modern organometallic
chemistry and are capable of stabilizing various metal complexes in multiple oxidation states …

Early-transition-metal hydrogenation catalysts have received less attention than comparable
late-transition-metal systems, particularly since the discovery of Wilkinson s catalyst.[1] This …

While niobium and tantalum are found together in their mineral ores, their respective
applications in technology require chemical separation. Nb/Ta separations are challenging …

The discovery of a Nb (III)-mediated catalytic hydrogenation of internal alkynes to (Z)-
alkenes that proceeds through an unprecedented mechanism is reported. The mechanistic …

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) …

The bis (imido) complexes (BDI) Nb (NtBu) 2 and (BDI) Nb (NtBu)(NAr)(BDI= N, N′-bis (2, 6-
diisopropylphenyl)-3, 5-dimethyl-β-diketiminate; Ar= 2, 6-diisopropylphenyl) were shown to …

The mechanism of activation of C–F bonds in fluoroarenes using a well-defined niobium (III)
imido complex has been investigated. The Nb (III) arene species [BDI] Nb (NtBu)(η6-C6H6) …

Niobium complexes in organic reactions have received a lot of attention in recent years.
Niobium is one of the early transition metals, which possess unique reactivity distinct from …
