NMR study of the reactivity of multifunctional ligand cis,cis-C6H9(NHCH2C6H4-o-PPh2)(3) (1) with GaMe3 and Zr(NMe2)(4) was carried out, yielding [cis,cis-(kappa(N)-NHCH2C6H4-o-PPh2)(kappa(N)-NCH2C6H4-o-PPh2)(2)C6H9] GaMe (2) and [cis,cis-(NCH2C6H4-o-PPh2)(3)C6H9] Ga2Me3 (3), and [cis,cis-(NCH2C6H4-o-PPh2)(3)C6H9]Zr (NMe2) (4), respectively. The spectral properties of 2 and 3 are very similar to that observed for the equivalent aluminum species already reported, but form at a much slower rate which allows for the observation of a GaMe3.1 adduct. Species 4 undergoes coordination/displacement of one of the phosphine arms, which was observed using both NMR spectroscopy and DFT analyses. (C) 2010 Elsevier B.V. All rights reserved.
