Synthesis and structures of zirconium and hafnium alkyl complexes that contain [H3CC(2-C5H4N)(CH2NAr)2] 2- ([ArNpy]2-; Ar = Mesityl, triisopropylphenyl) ligands

We report the synthesis of the arylated diamidopyridine ligands [H3CC(2-C5H4N)(CH2NAr)2] 2- ([ArNpy]2-; Ar = 2,4,6-Me3C6H2 (Mes), 2,4,6-(i-Pr)3C6H2 (Trip)). [ArNpy]M(NMe2)2 (M = Zr, Hf) complexes were prepared by treating M(NMe2)4 with H2[ArNpy], while [ArNpy]MCl2 was prepared in a reaction between [ArNpy] M(NMe2)2 and Me3SiCl. Zirconium dialkyl complexes that were prepared include [MesNpy]ZrR2 (R = methyl, benzyl, neopentyl, isobutyl), [MesNpylZr(THF)Me2, [Li(Et2O)]{[MesNpy]ZrMe3}-, and [TripNpy]Zr(i-Bu)2. Hafnium [MesNpy]HfR2 complexes are relatively stable, even when β-protons are present in R (R = Me, Et, n-Pr, n-Bu, i-Bu, i-Pr). Monoalkyl monochloro hafnium complexes that were prepared include [MesNpy]Hf(i-Pr)Cl and [MesNpy]Hf(t-Bu)Cl. X-ray studies were carried out for [MesNpy]ZrMe2, [MesNpy]Zr(THF)Me2, [Li(Et2O)]{[MesNpy]ZrMe3}, [TripNpy]Zr(i-Bu)2, [MesNpy]Hf(i-Pr)Cl, and [MesNpy]Hf(i-Pr)2.
