C-H Bond Activation of Benzene by Unsaturated η-Cyclopropene and η-Benzyne Complexes of Niobium.

We report the synthesis of a niobium cyclopropyl complex, TpNbMe(c-CH)(MeCCMe), and show that thermal loss of methane from this compound generates an intermediate that is capable of activating both aliphatic and aromatic C-H bonds. Isotopic labeling, trapping studies, a detailed kinetic analysis, an...
