The cyclometallated tantalum hydride complex 1  has been prepared by hydrogenolysis of a tantalum dimethyl precurser. The reactivity of this compound has been investigated in the hopes that it would behave as a source for reactive low-coordinate Ta(III) species via C-H reductive elimination. The complex undergoes reductive elimination under certain conditions to give reactive trivalent tantalum species. Under different conditions, 1  exhibits insertion reactivity to give unusual metallacyclic products. Synthesis and characterization of new compounds, as well as mechanistic details will be discussed.
