Reduced Arene Complexes of Hafnium Supported by a Triamidoamine Ligand.

ABSTRACT: A series of hafnium complexes with a reduced arene of the general formula [K(L)][Hf(Xy-N₃ N)(arene)] (Xy-N₃ N={(3,5-Me₂ C₆ H₃ )NCH₂ CH₂ }₃ N^3- , L=THF, 18-crown-6; arene=C₁₀ H₈ ^2- , C₁₄ H₁₀ ^2- ) mimic the chemistry of hafnium in its formal oxidation state +II. All compounds were obtained upon reduction of the chlorido complex [HfCl(Xy-N₃ N)(thf)] with two equivalents of potassium naphthalenide or anthracenide. The reducing nature and the basicity of the reduced anthracene ligand were explored in the reaction of benzonitrile and azobenzene, and by deprotonation of tert-butylacetylene, respectively. The reduction of be
