摘要：

Trapping of the tantalocene borataalkene complex Cp2Ta[CH2B(C6F5)(2)] with 2 equiv of cyclohexyl or benzyl isocyanide gives Ta(III) products where the metallocene fragment is ligated by an eta(3)-1-azaallyl ligand incorporating an iminoacyl boryl fragment on the central carbon atom. This unique ligand assembly arises via reaction of the isocyanide reagent with the eta(1) form of the borataalkene ligand, demonstrating a new reactivity mode for this relatively unexplored class of boratahydrocarbon ligands.
