Low-valent niobium chemistry: synthesis of bent bis-arene niobium alkyl and halide complexes, half-sandwich mono-arene niobium tertiary phosphine compounds, and related studies

Abstract

The syntheses of the new compounds [Nb(η-C₆H₅Me)₂X](X = Me, Ph, Br, I), [Nb(η-C₆H₅Me)(PMe₃)₃X (X = H, SiMe₃), [Nb(η-C₆H₅Me)(η⁵-C₇H₉)(PMe₃)], and [Nb(η-C₇H₇)(CO)₂(PMe₃)] are described.
