a b s t r a c t NMR study of the reactivity of multifunctional ligand cis,cis-C 6 H 9 (NHCH 2 C 6 H 4 -o-PPh 2 ) 3 (1) with GaMe 3 and Zr(NMe 2 ) 4 was carried out, yielding [cis,cis-(9 ]Zr (NMe 2 ) (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 GaMe 3 ,1 adduct. Species 4 undergoes coordination/displacement of one of the phosphine arms, which was observed using both NMR spectroscopy and DFT analyses.
