Four new aminotroponiminato hafnium and zirconium tribenzyl complexes were prepared by reacting neutral ligands with the corresponding tetrabenzyl complexes. Aminotroponimine ligands were prepared in four steps starting from tropolone. An air-stable ethoxy-amino-tropylium cation intermediate isolated during ligand synthesis was found to react directly with amines significantly faster than the neutral
