Reactions of d° Group 4 Amides with Dioxygen. Preparation of Unusual Oxo Aminoxy Complexes and Theoretical Studies of Their Formation.
Reactions of d amides M(NMe) (M = Zr, 1; Hf, 2) with O have been found to yield unusual trinuclear oxo aminoxide complexes M(NMe)(μ-NMe)(μ-O)(μ-ONMe) (M = Zr, 3; Hf, 4) in high yields. Tetramethylhydrazine MeN-NMe was also observed in the reaction mixtures. Crystal structures of 3 and 4 have been de...

Tetramethylhydrazine MeN-NMe was also observed in the reaction mixtures. Crystal structures of 3 and 4 have been determined. Density functional theory calculations have been performed to explore the mechanistic pathways in the reactions of model complexes Zr(NR) (R = H, 5; Me, 1) and [Zr(NR)] (R = H, 5a; Me, 1a) with triplet O. Monomeric and dimeric reaction pathways in the formation of the Zr complex 3 are proposed. pubtype: Academic Journal doctype: Article src: R language: English refInfo: copyright: @attributes: flag: Y dt: @attributes: year: 2005 holdings: @attributes: islocal: N |
