Reaction of the dimeric zirconium imido compound [Zr2(μ-NAr) 2Cl4(THF)4] with tris(3,5-dimethylpyrazolyl) methyl silane very selectively gave [Zr{(Me2pz)2Si(Me)NAr} Cl3] (1), a highly active pre-catalyst for ethylene polymerisation; a more general and versatile route to N3 donor heteroscorpionate compounds was achieved via the protio ligand (Me2pz) 2CHSi(Me)2N(H)iPr for which neutral and cationic organometallic Group 3 and 4 derivatives are reported (Ar = 2,6-C 6H3iPr2).
