The reaction of 2,6-diisopropylaniline-based bisimine ligands (4, 9) with M(CH2Ph)4 (M = Hf, Zr) led to formation of novel imino - amido tribenzyl complexes via migratory insertion of a benzyl group into a C=N bond. Imino - amido complexes were found to undergo unprecedented dibenzyl elimination to form ene - diamido complexes. Imino - amido complexes were found to be active ethylene polymerization catalysts.
