New triamidoamine-supported (N3N = N(CH2CH2NSiMe3)33–) complexes of zirconium and hafnium bearing alkyl ligands have been prepared. Upon heating, these complexes undergo metallation of the triamidoamine ligand with elimination of R–H. The resulting complexes, [eta5-(Me3SiNCH2CH2)2NCH2CH2NSiMe2CH2]M (M = Zr, Hf), react with main group hydrides to give species with terminal M–E bonds (E = P, As, Sb). These complexes undergo reactions with a variety of small molecule substrates and serve as catalysts in bond-forming reactions.
