摘要：

Treatment of the 4e-alkyne complex [Tp*Nb-(CO)(2)(PhCCMe)] with the nitrile RCN (R = Ph, Me, Et) yields the first mixed 3e-alkyne-eta(2)(3e)-nitrile complexes, [TP*Nb(CO)(PhCCMe)(RCN)], which have been spectroscopically and structurally characterized. Upon addition of HBF4, the protonated coupling product [Tp*Nb-(F)(CPhCMeCPhNH] (R = Ph) is formed.
