Dis-assembly of a benzylic CF3 group mediated by a niobium(III) imido complex.

Thomas L Gianetti1, Robert G Bergman, John Arnold.   

Abstract

All three C-F bonds in CF3-substituted arenes are activated by a niobium imido complex, driven by the formation of strong Nb-F bonds. The mechanism of this transformation was studied by NMR spectroscopy, which revealed the involvement of Nb(III). Attempts to extend this chemistry to nonaromatic CF3 groups led to intramolecular reactivity.
