In this paper we report the synthesis and chemistry of a series of new {eta}{sup 4}-cyclohexadiene derivatives of niobium and tantalum containing aryl oxide ligation. This synthetic work is complemented by an investigation of the reactivity of previously isolated tantalum hydride compounds as well as related niobium catalysts toward 1,3-cyclohexadiene and cyclohexene. The studies reported here focus on gaining a better insight into the overall mechanism of arene hydrogenation by this specific pedigree of catalyst. The mechanistic implications of stoichiometric and catalytic reactions are discussed. 48 refs., 8 figs., 6 tabs.
