The preparation and reactivity of group 5 indenyl complexes
The preparation of tri-n-butylstannylindene, has led to new synthetic routes to obtaining indenyl metal complexes of the Group V metal halides. Also, the fluxional behavior of tri-n-butylstannylindene has been studied by variable temperature 1H NMR spectroscopy.The interaction of the Group V metal halides with tri-n-butylstannylindene has led to the isolation and characterization of [(q5-C9H7)2TaC12] [TaC16] and [('q5-C9H7)2NbC12] [NbCl6]. Subsequent Lewis base chemistry has produced (T15-C9H7)TaC14(PMe3). The crystal structures of [(r15-C9H7)2TaCl2] [TaC16] and (15-C9H7)TaC14(PMe3) have been determined. The preparation and characterization of these compounds are discussed as well as the exploratory indenyl, Lewis base, and /or salt chemistry of vanadium, niobium, and tantalum.
